Let the graph of g be a vertical stretch by a factor of 3 and a reflection in the y-axis of the graph of f(x) = x2 Write a rule for g.
9(20)
= 3x2
Og(x)
- (3x)²
g(x)
3.22
O g(x) = (-3c)? 2

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
