9 = 2(2x + 4)2, 9 = 2(4x2 + 16x + 16), 9 = 8x2 + 32x + 32 How did the 16x come about?
The coordinates of the x-intercepts given are (-1,0) and (3,0). The y-intercept is 2.5. How do you create an equation in standard and vertex form with that info? I'm not sure what each...
how do i solve this?
determine value of k when g(x)= 4x+k does not intersect the parabola f(x)=-3x2-x+4
3/7 and -4
Solve: x^3 +2x^2 +x > or = 0 Step by step assistance would be amazing!
