Factor 6x3 - 9x2 - 4x + 6
(2x - 3)(3x2 - 2)
Alec bought a used car for $7600. The car’s value decreases at a constant rate each year. After 10 years, the value decreased to $3600. Find the amount that the value decreases each year.
slope = -400
G(x)=4x+4; find G(x)+4
G(x)+4 = 4x+8
What is the range?
(-∞, 4]
What is the domain?
(-∞,∞)
Factor 4x3 - 4x2 - 120x
4x(x - 6)(x + 5)
Alec bought a used car for $7600. The car’s value decreases at a constant rate each year. After 10 years, the value decreased to $3600. Find the range of the function in this context.
[0, 7600]
F(x)=7-5x2; find F(2)

(x - 3)(x+3)(x2 + 9)
Alec bought a used car for $7600. The car’s value decreases at a constant rate each year. After 10 years, the value decreased to $3600. Find the domain of the function in this context.
[0,∞) or [0,19]
g(x)=4x2-3; find g(x+2)
g(x+2)=4(x2+4x+4)-3 = 4x2+16x+13
Solve f(x) = 3
