Question

This is the graph of f(x)=-0.05(x^ 1 2-26x-120 .What are the zeros of this function? Circle them on the graph

Answer 1

Answer:

Zeros are at x = 30 and x = -4.

Explanation:

The zeros of a function are the points where it intersects the x-axis. in other words, the zeros are solutions to the following equation.

$f(x)=0.$

which in our case is

$f\mleft(x\mright)=-0.05\left(x^2-26x-120\right)=0$

Now looking that the graph of the function given we see that the parabola intersects the x-axis at x = -4 and x = 30.

Therefore, the zeros of the function are at x = -4 and x = 30.
