1. Problem Description

We are given two functions g(x)=6x+1g(x) = -6x + 1 and h(x)=5x+6h(x) = -5x + 6. We need to evaluate g(3)g(-3), h(3)h(-3), g(h(x))g(h(x)), and g(h(3))g(h(-3)).

2. Solution Steps

First, we calculate g(3)g(-3) by substituting x=3x = -3 into the expression for g(x)g(x):
g(3)=6(3)+1=18+1=19g(-3) = -6(-3) + 1 = 18 + 1 = 19.
Next, we calculate h(3)h(-3) by substituting x=3x = -3 into the expression for h(x)h(x):
h(3)=5(3)+6=15+6=21h(-3) = -5(-3) + 6 = 15 + 6 = 21.
Now, we calculate g(h(x))g(h(x)) by substituting h(x)h(x) into the expression for g(x)g(x):
g(h(x))=g(5x+6)=6(5x+6)+1=30x36+1=30x35g(h(x)) = g(-5x + 6) = -6(-5x + 6) + 1 = 30x - 36 + 1 = 30x - 35.
Finally, we calculate g(h(3))g(h(-3)). We already know h(3)=21h(-3) = 21, so we need to calculate g(21)g(21):
g(h(3))=g(21)=6(21)+1=126+1=125g(h(-3)) = g(21) = -6(21) + 1 = -126 + 1 = -125.

3. Final Answer

g(3)=19g(-3) = 19
h(3)=21h(-3) = 21
g(h(x))=30x35g(h(x)) = 30x - 35
g(h(3))=125g(h(-3)) = -125
