Q. The functionsff and gg are defined asf(x)=x2f(x)=x-2,g(x)=x+3g(x)=\sqrt{x+3}.\newlinea) Find the domain of \newlineff,gg,f+gf+g,fgf-g,fgfg,f2f^2,gg00, and gg11.\newlineb) Find \newlinegg22,gg33,gg44,gg55,gg66, and gg77.
  1. Find Domain of f(x)f(x): To find the domain of f(x)=x2f(x) = x - 2, we need to determine the set of all xx-values for which f(x)f(x) is defined.\newlineSince f(x)f(x) is a polynomial function, it is defined for all real numbers.
  2. Find Domain of g(x): To find the domain of g(x)=x+3g(x) = \sqrt{x + 3}, we need to determine the set of all xx-values for which g(x)g(x) is defined.\newlineThe square root function is defined for non-negative arguments, so x+3x + 3 must be greater than or equal to 00.\newlineSolving the inequality x+30x + 3 \geq 0 gives us x3x \geq -3.\newlineTherefore, the domain of g(x)g(x) is all real numbers xx such that x3x \geq -3.
  3. Find Domain of f+gf + g: To find the domain of f+gf + g, we need to find the intersection of the domains of ff and gg. Since the domain of ff is all real numbers and the domain of gg is x3x \geq -3, the domain of f+gf + g is x3x \geq -3.
  4. Find Domain of fgf - g: To find the domain of fgf - g, we again find the intersection of the domains of ff and gg. The domain of fgf - g is also x3x \geq -3.
  5. Find Domain of fg: To find the domain of fg, we find the intersection of the domains of f and g.\newlineThe domain of fg is x3x \geq -3.
  6. Find Domain of f ullet f: To find the domain of f ullet f (ff composed with ff), we consider the domain of ff, which is all real numbers. Since ff is defined for all real numbers, the domain of f ullet f is also all real numbers.
  7. Find Domain of (f)/(g)(f)/(g): To find the domain of (f)/(g)(f)/(g), we need to find the intersection of the domains of ff and gg, and exclude any xx-values for which g(x)=0g(x) = 0.\newlineSince g(x)=x+3g(x) = \sqrt{x + 3}, g(x)g(x) is zero when x=3x = -3.\newlineTherefore, the domain of (f)/(g)(f)/(g) is (f)/(g)(f)/(g)00.
  8. Find Domain of (g)/(f)(g)/(f): To find the domain of (g)/(f)(g)/(f), we need to find the intersection of the domains of ff and gg, and exclude any xx-values for which f(x)=0f(x) = 0.\newlineSince f(x)=x2f(x) = x - 2, f(x)f(x) is zero when x=2x = 2.\newlineTherefore, the domain of (g)/(f)(g)/(f) is (g)/(f)(g)/(f)00 and (g)/(f)(g)/(f)11.
  9. Calculate (f+g)(x)(f+g)(x): Now we will calculate (f+g)(x)=f(x)+g(x)=(x2)+x+3(f+g)(x) = f(x) + g(x) = (x - 2) + \sqrt{x + 3}.
  10. Calculate (fg)(x)(f-g)(x): Next, we calculate (fg)(x)=f(x)g(x)=(x2)x+3(f-g)(x) = f(x) - g(x) = (x - 2) - \sqrt{x + 3}.
  11. Calculate (fg)(x)(fg)(x): Then, we calculate (fg)(x)=f(x)g(x)=(x2)x+3(fg)(x) = f(x) \cdot g(x) = (x - 2) \cdot \sqrt{x + 3}.
  12. Calculate (ff)(x)(ff)(x): For (ff)(x)(ff)(x), we calculate f(f(x))=f(x2)=(x2)2=x4f(f(x)) = f(x - 2) = (x - 2) - 2 = x - 4.
  13. Calculate (fg)(x)\left(\frac{f}{g}\right)(x): To calculate (fg)(x)\left(\frac{f}{g}\right)(x), we find f(x)g(x)=x2x+3\frac{f(x)}{g(x)} = \frac{x - 2}{\sqrt{x + 3}}, for x > -3.
  14. Calculate (gf)(x)\left(\frac{g}{f}\right)(x): Finally, to calculate (gf)(x)\left(\frac{g}{f}\right)(x), we find g(x)f(x)=x+3x2\frac{g(x)}{f(x)} = \frac{\sqrt{x + 3}}{x - 2}, for x3x \geq -3 and x2x \neq 2.
