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:

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

Solve for X, will mark brainliest if right

Vitek1552 [10]

Answer:

x = 8

Step-by-step explanation:

The sides are in proportion.

$\frac{RG}{FG} =\frac{SH}{FH}$
40 / 7x + 14 = 44 / 33 + 44
40 / 7x + 14 = 44/77 = 4/7
40(7) = 4(7x + 14)
280 = 28x + 56
10 = x + 2
x = 8
