Question

GRAPH THE QUADRATIC FUNCTION LABEL THE VERTEX AXIS 0OF SYMMETRY AND X INTERCEPTS IDENTIFY DOMAIN & RANGE OF FUNCTION Y=2(X+1)(X-3)

Answer 1

It is a parabola, right?
You can plot some points to graph it.
Look at what happens when X=-1 and X=1 and X=3
The X intercepts are where Y=0 (should be two of them)
Are there some values of X that you cannot use?
What is the smallest value of Y you can get out of it?
