Answer:
g(x) = 6x^2-1
Step-by-step explanation:
f(x)=3/4x^2 −1.
A vertical stretch by a factor of 8 you multiply the number with x by the factor:
3/4 x 8 = 6
y = 6x + 3 --------------(I)
x + 2y = 5 -------------(II)
substitute y = 6x + 3 in equation (II)
x + 2*(6x + 3) = 5
x + 2*6x + 2*3 = 5
x + 12x + 6 = 5
13x + 6 = 5
