Q. Find all x-intercepts of the following function. Write your answer or answers as coordinate points. Be sure to select the appropriate number of x-intercepts.f(x)=5x−82x−4
Set Equation to Zero: To find the x-intercepts of the function, we need to set f(x) to zero and solve for x. This is because x-intercepts occur where the graph of the function crosses the x-axis, which corresponds to the points where the function value is zero.
Solve for x: Setting f(x) to zero gives us the equation 5x−82x−4=0. To find the x-intercepts, we need to solve this equation for x.
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: 2x−4=0.
Isolate x: Solving the equation 2x−4=0 for x, we add 4 to both sides to get 2x=4.
Find x-Intercept Coordinate: Next, we divide both sides by 2 to isolate x, which gives us x=2.
Find x-Intercept Coordinate: Next, we divide both sides by 2 to isolate x, which gives us x=2.Now that we have the value of x, we can write the x-intercept as a coordinate point. The x-intercept is at the point (2,0).
