Question

Graph the function f(x)=3(x+3)^2

Answer 1

See below.

Explanation:

The vertex is (h,k) in the vertex form
`y = a(x-h)^2+k`. Here it is (-3,0).

Then substitute a value into the function to find another point on the parabola.

Choose x = 0.

y = 3(0+3)^2

y = 3(3)^2

y = 3(9)

y = 27

The point is (0, 27).
