Question

given that f(x)=-x+4 and g(x)=-2x-3, solve for f(g(x)) when x=2

Answer 1

f(g(x)) = f(-2x-3) = -(-2x-3) + 4 = 2x+3+4 = 2x + 7

Keep in mind, that when we want f(-2x-3), we want the value of f, when x takes on a value of -2x-3, so just replace x with -2x-3.

Answer 2

that's the answer ? @Easyaspi314

Answer 3

yes, answer is 2x + 7. Any questions how I got it?
