Can some please help me solve this please

f(3) = 16 and f(4) = 23

Step-by-step explanation:

Finding f(3) simply means we're finding the value of the function when x = 3, so we can plug 3 in for x in our function:

f(3)

, so now we have:

f(3) = 9 + 7

9 + 7 = 16, so f(3) = 16.

Now we want to find the value of x that makes the function equal 23, so let's set our function equal to 23:

We want to get x by itself in order to find the value, so let's start by subtracting 7 from both sides:

23 - 7 =

23 - 7 = 16, so 16 =

Now, we can take the square root of both sides:

, so now we have:

4 = x
