Please help me

if v=6, w=-9, and x=7

Write the equation for the parabola that has x− intercepts (−2,0) and (4,0) and y− intercept (0,4).

1. evaluate 8x(2)y9(-2) for x=-1 and y=2 2. simplify the equation. -() 3. simplify the expression. [tex]\frac{5}{x(-2) y9(5)}[/tex]

I’m really confused and need to learn this
