Answer:
g(x)=8.5([tex]x^{2}[/tex]+4)
Step-by-step explanation:
vertical stretch means to put that number in front like this:
8.5(x^2)
Then 4 units to the left means it will look like this. (Translation to the left is plus in the parentheses and for the right it's negative in the parentheses.)
8.5(x^2+4)
So you full equation is:
g(x)=8.5(x^2+4)
