Question

Suppose that the x-intercepts of the graph of y = f(x) are 6 and 5. What are the x-intercepts of

y = f(-x)?

Answer 1

The x-intercepts of f(-x) are -6 and -5

Explanation:

we know that

The x-intercepts of f(x) are

x=5, x=6

That means

x-5=0

x-6=0

Substitute the variable x by -x

-x-5=0 ----> x=-5

-x-6=0 ----> x=-6

therefore

The x-intercepts of f(-x) are -6 and -5
