Given f(x) = -x + 2, find f(-1)
jarptica [38.1K]

f(x) = -x + 2

f(-1)   This means that they want you to find the value of f(x) or y when x = -1.

f(x) = -x + 2     Substitute/plug in -1 into "x" since x = -1

f(-1) = -(-1) + 2     (two negative signs cancel each other out and become positive)

f(-1) = 1 + 2

f(-1) = 3

If s(x) = 2x2 + 3x - 4, and t(x) = x + 4 then s(x) · t(x) =
Nookie1986 [14]
You simply multiply the two and distribute to solve. I am starting with t(x) because I think it is easier.

(x+4)*(2x^2+3x-4) 
2x^3+3x^2-4x+8x^2+12x-16 (distribute)
2x^3+11x^2+8x-16 (combine like terms)
