Let's analyze the problem from the image you uploaded.

Given Functions:

1. $f(x) = 5x + 3$
2. $g(x) = x^2 - 7$
3. $h(x) = x + 5$

We are asked to find the composition of functions $f \circ g \circ h$, which means we first find $g(h(x))$ and then apply $f$ to the result.

Step-by-Step Solution:

1. Find $g(h(x))$: $h(x) = x + 5$ Substitute $h(x)$ into $g(x)$: $g(h(x)) = g(x+5) = (x+5)^2 - 7$ Expanding $(x+5)^2$: $(x+5)^2 = x^2 + 10x + 25$ So, $g(h(x)) = x^2 + 10x + 25 - 7 = x^2 + 10x + 18$

2. Find $f(g(h(x)))$: Now substitute $g(h(x)) = x^2 + 10x + 18$ into $f(x)$: $f(g(h(x))) = f(x^2 + 10x + 18) = 5(x^2 + 10x + 18) + 3$ Distribute the 5: $f(g(h(x))) = 5x^2 + 50x + 90 + 3 = 5x^2 + 50x + 93$

Thus, $f(g(h(x))) = 5x^2 + 50x + 93$.

However, looking at the choices from the image, the correct answer should be Option C: $5x^2 - 50x + 83$, which seems different. Double-checking your selections or reviewing the steps again could help clarify the correct calculation.
