Answer: (x-9)(x+1), so x=9 and x=-1
Step-by-step explanation:
X^2-8x-9=0
-9 times 1 = -9 and -9 plus 1 = -8
So (x-9)(x+1)
X=9, x=-1
Answer:

Answer:
h(1) = 1, h(2) = 3, h(3) = 4
Step-by-step explanation:
Given function h(x)
<u>Need to find :</u>
<u>h(1) falls under the second condition as -2 ≤1<2:</u>
- h(1) = - (x-1)² + 1 = -( 1 - 1)² + 1 = 1
<u>h(2) and h(4) fall under the third condition as x=2,4 ≥ 2:</u>
- h(2) = 1/2x + 2 = 1/2*2 + 2 = 1 + 2 = 3
- h(4) = 1/2x + 2 = 1/2 * 4 + 2 = 2 + 2 = 4
Answer: Linear
Step-by-step explanation:
Linear means that in an equation, the highest power of x is 1. Or, there are no x^2, x^3, etc. Only x^1. Quadratic means that the highest power of x is 2. This is also called the degree. The degree is the highest power of x.
