Given f(x) = x − 7 and g(x) = x2 . find g(f(

The value of the g(f(4)) is 9 .

Step-by-step explanation:

As given the expression in the question be as follow.

f(x) = x − 7

g(x) = x²

Now find g(f(4)).

First find f(4) .

f(4) = 4 - 7

      = -3

Thus

g(f(4)) = (-3)²

As

(-3)² = 9

Put in the above expression

g(f(4)) = 9

Therefore the value of the g(f(4)) is 9 .

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
