Q. Find all x x -intercepts of the following function. Write your answer or answers as coordinate points. Be sure to select the appropriate number of x x -intercepts.\newlinef(x)=2x45x8 f(x)=\frac{2 x-4}{5 x-8}
  1. Set Equation to Zero: To find the xx-intercepts of the function, we need to set f(x)f(x) to zero and solve for xx. This is because xx-intercepts occur where the graph of the function crosses the xx-axis, which corresponds to the points where the function value is zero.
  2. Solve for xx: Setting f(x)f(x) to zero gives us the equation 2x45x8=0\frac{2x-4}{5x-8} = 0. To find the xx-intercepts, we need to solve this equation for xx.
  3. Ignore Denominator: Since a fraction is only equal to zero when its numerator is zero, we can ignore the denominator for this step and set the numerator equal to zero: 2x4=02x - 4 = 0.
  4. Isolate x: Solving the equation 2x4=02x - 4 = 0 for xx, we add 44 to both sides to get 2x=42x = 4.
  5. Find x-Intercept Coordinate: Next, we divide both sides by 22 to isolate xx, which gives us x=2x = 2.
  6. Find x-Intercept Coordinate: Next, we divide both sides by 22 to isolate xx, which gives us x=2x = 2.Now that we have the value of xx, we can write the x-intercept as a coordinate point. The x-intercept is at the point (2,0)(2, 0).
