Let f(x)=-6x+3 and g(x)=5x+4 find f×g and state it's domain

a) -18x^2-39x+20; all real numbers except x=1

b) -30x^2-9x+12; all real numbers except x=4

c) -30x^2-9x+12; all real numbers

d) -18x^2-39x+20; all real numbers

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
