Let f(x) = -5x + 3 and g(x) = 6x – 2. Find f * g and its domain.

Question

A. -30x^2 + 28x - 6; all real numbers except x = 1/3
B. -15x^2 - 8x - 12; all real numbers except x = 3/5
C. -30x^2 + 28x - 6; all real numbers**
D. -15x^2 -8x - 12; all real numbers

Answer 3

f(x) = -5x + 3 and g(x) = 6x – 2.
f*g
= (-5x+3)(6x-2)
= -30x^2 + 28x - 6

the correct answer is C

don't know what the bot is going on about "except x = 1/3"
the domain is the set of reals
