Question

Which of the following are the xintercepts on the graph of the function shown below? f(x)=(x+2)(x-7)

Answer 1

Which of the following are the xintercepts on the graph of the function shown below? f(x)=(x+2)(x-7)​

we have the function

f(x)=(x+2)(x-7)​

This is a vertical parabola written in factored form

The zeros or x-intercepts of the function are

x=-2 and x=7

Remember that the x-intercepts are the values of x when the value of the function is equal to zero

therefore

the answer is

x=-2 and x=7
