Quadratic Function y = a(x – h)2 + k a h k 1. y = x2 + 8x + 20

2. y = – x

2 – 6x – 10

3. y = 2x2 + 20x + 51

4. y = –2x (x + 1) + 3

5. y = (–x

2 – 2x + 1) + (7–

Brent needs to paint a logo made using two right triangles. the dimensions of the logo are shown below. what is the difference between the area of the large triangle and the area of the small triangle? (1 point) select one: a. 4.5 cm2 b. 8.5 cm2 c. 16.5 cm2 d. 33.0 cm2

Which describes the difference between the graph of f(x)=x^2 and g(x)=-(x^2-2)

How do i simply this expression (quadratic formula basis) on a ti-84 or normal calculator?
