Step-by-step explanation:
Answer:
1. (2x^2+x-1)
Step-by-step explanation:
expanding (2x^2-1)^2. multiplying (x-2) (1-2x)
= 4x^2-4x+1. = x-2x^2-2+4x
= -2x^2+5x-2
(4x^2-4x+1-2x^2+5x-2)
=2x^2+x-1
Answer:
y=2x-3
Step-by-step explanation:
the negative 3 represents the y intercept and the 2 represents the slope.
The distributive property: a(b + c) = ab + ac
8 × 19 = 8 × (20 - 1) = 8 × 20 - 8 × 1 = 160 - 8 = 152
(f○g)(x)=f(g(x))
(f○g)(x)=3(x^2+4)+2
(f○g)(x)=3x^2+12+2
(f○g)(x)=3x^2+14
