Verified Answer :

1.) \(g(x)=4x^2+2\)
2.) \(g(x)=3/4x^2+7\)

Answer:

1 - \(g(x)=4x^2+2\).

2 - \(g(x)=6x^2-8\)

Step-by-step explanation:

Ques 1: We are given the function, \(f(x)=4x^2+6\)

Now, we have, the function f(x) is translated 4 units down to get the function g(x).

Thus, the translated function is, \(g(x)=4x^2+6-4\).

That is, the translated function is, \(g(x)=4x^2+2\).

Ques 2: We are given the function, \(f(x)=\frac{3}{4}x^2-1\)

Now, we have, the function f(x) is stretched vertically by a factor of 8 to get the function g(x).

Thus, the stretched function is, \(g(x)=8\times (\frac{3}{4}x^2-1)\)

That is, the stretched function is, \(g(x)=6x^2-8\)
