Answer:
(a) -6
Step-by-step explanation:
P(x) = ax^3 +bx - 3
- P(-1) = -a-b-3 = 0
- therefore a+b=-3
- P(1) = a+b-3
- P(1) = -3 - 3 = -6
- (a)
Answer:
Use distributive property:
-6x+12
Answer:
x=-1
Step-by-step explanation:
x+1=0(squared).
x+1=0 (anything raise to the power 0 is 0
collect like terms =x=-1
therefore x=-1

Therefore, the slope of the line is 1. In case if you want to know the equation.

Therefore, the equation is y=x+10 by substituting the (-6,4) or we can substitute (6,16) too.

It's the same, you can use any orders given.
Overall, the slope is 1 and the equation is y=x+10
Answer:
f(x) = - 4x² + 24x - 20
Step-by-step explanation:
Given
f(x) = - 4(x - 3)² + 16 ← expand the factor using FOIL
= - 4(x² - 6x + 9) + 16 ← distribute parenthesis by - 4
= - 4x² + 24x - 36 + 16 ← collect like terms
= - 4x² + 24x - 20
