f(x)=4x-2 and g(x)=2x+1
f(-3)/g(-5)
So first let's find f(-3). Since f(x) = 4x-2 and we want f(-3), just plug in -3 everywhere you see x. So you would get:
f(-3) = 4(-3) - 2
f(-3) = -12 - 2
f(-3) = -14
Now, let's find g(-5). Since g(x) = 2x+1 and we want g(-5), just plug in -5 everywhere you see x. So you would get:
g(-5) = 2(-5) + 1
g(-5) = -10 +1
g(-5) = -9
So to find f(-3)/g(-5) lets plug in the numbers we got for f(-3) and g(-5).
f(-3)/g(-5) = -14/-9 = 14/9
