Answer:

f(-7) = -3

Step-by-step explanation:

The exponentiation x^2 must be done before multiplication by the coefficient -1.

Substituting -7 for x, we get:

-(-7)^2 + 6(-7) + 4 = f(-7)

Then f(-7) = -49 + 42 + 4, or

f(-7) = -3

If f(x) = x ^ 2 is vertically compressed by a factor of 9 to g(x) , what is the equation of g(x) ?

Maslowich

Answer:

$g(x) = \frac{1}{9} \,x^2$ which agrees with option A in the list of possible answers

Step-by-step explanation:

A vertical compression by a factor 9 is represented by the transformation:

$\frac{1}{9} \,f(x) = \frac{1}{9} \,x^2$

Therefore the answer to the problem is:

$g(x) = \frac{1}{9} \,x^2$
