Question

Find the x-values for which f(x) = g(x)
if you know that f(x) = x2 and g(x) = 9.

Answer 1

For the values of x = 3 and x = -3 the given functions f(x) = g(x)

Explanation:

Here, the given functions are

`f(x)  = x^(2) \\g(x) = 9`

Now, given f(x) = g(x)

⇒
`x^(2)   = 9`

or,
`x = √(9)   \implies x  = 3, -3`

Hence, for the values of x = 3 and x = -3 the given functions f(x) = g(x)
