Hey there! :)
Answer:
f(-2) = -148.
Step-by-step explanation:
To calculate f(-2), simplify substitute -2 for x in the equation. Therefore:
f(x) = 4x³ -12x² + 40x + 12
Becomes:
f(-2) = 4(-2)³ - 12(-2)² + 40(-2) + 12
Simplify:
f(-2) = 4(-8) - 12(4) - 80 + 12
f(-2) = -32 - 48 -80 + 12
Finally, you get:
f(-2) = -148.
Answer:
y-2=1/3(x-3)
Step-by-step explanation:
y-y1=m(x-x1)
y-2=1/3(x-3)
Answer:
A) -8x^2 - 26x - 15
Step-by-step explanation:
(4x + 3)(-2x - 5)
FOIL
first: 4x*-2x = -8x^2
outer : -5*4x = -20x
inner: -2x*3 = -6x
last: -5*3 = -15
Add these together
-8x^2 -20x-6x -15
-8x^2 -26x-15
