Answer:
f(x) = -(x+2)(x-1)
Step-by-step explanation:
We know the zeros are at 1 and -2
f(x) = a *(x-b1)(x-b2) where b1 and b2 are the zeros and a is a constant
f(x) =a(x-1)(x- -2)
f(x) =a(x-1)(x+2)
We know that a must be negative since the parabola opens down so
The only choice is choice D where a = -1
f(x) = -(x+2)(x-1)
Answer:
C
Step-by-step explanation:
calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (0, 2) and (x₂, y₂ ) = (4, 0) ← 2 points on the line
m = 
= 
= - 
the y- intercept is the value of y where the line crosses the y- axis , then
y- intercept = 2
Answer: 3y3+7y2+−4y+3
Step-by-step explanation:
3y2+y3+−5+4y2+−4y+2y3+8
Combine Like Terms:
=3y2+y3+−5+4y2+−4y+2y3+8
=(y3+2y3)+(3y2+4y2)+(−4y)+(−5+8)
=3y3+7y2+−4y+3
