If ƒ(x)= -2x and g(x) = 3x + 1, what is the value of ƒ(2) + g(-1)?

Question

Me and my friend can't figure out the answer to this problem on our homework. Help please?

Answer 1

What this means is what is the value when x = 2 in the first equation and -1 in the second when  they are added together.

In other words:

f(2) = -2 * 2

f(2) = -4, and

g(-1) = 3 * -1 +1

g(-1) -3 + 1

g(1) = -2

 

So we have -4 + (-2)

And that equals -6
