What is the a-value of the function, then determine if the graph opens up or down f (x) = 2 (x+3) 2+4?

Question 4 options:

a = 2, opens up

a = 2, opens down

a = 4, opens up

a = 4, opens down

Let f (x) = 4x2-5.

A new quadratic function g (x) is the function f (x) stretched vertically by a factor of 2.

What is the equation of this new function g (x) ?

Question 7 options:

g (x) = 4x2-3

g (x) = 8x2-10

g (x) = 4 (x+2) 2-5

g (x) = 8x2-5
