Substitute Functions: To find the composition of functions (g@h)(x), we need to substitute the function h(x) into the function g(x). This means we will replace every instance of x in g(x) with the expression that defines h(x).Write Functions: First, let's write down the functions g(x) and h(x) for clarity: g(x) = 9 + (5/4)x h(x) = 10x - 28 Now, we will substitute h(x) into g(x).Distribute and Simplify: Substitute h(x) into g(x): (g@h)(x) = g(h(x)) = 9 + (5/4)(h(x)) Now, replace h(x) with its expression: (g@h)(x) = 9 + (5/4)(10x - 28)Combine Terms: Next, distribute the (5/4) across the terms in the parentheses: (g@h)(x) = 9 + (5/4)*10x - (5/4)*28Simplify the expression by multiplying the constants: (g@h)(x) = 9 + (50/4)x - (140/4) (g@h)(x) = 9 + (50/4)x - 35Combine the constant terms: (g@h)(x) = 9 - 35 + (50/4)x (g@h)(x) = -26 + (50/4)x

(g \circ h)(x)=

Substitute Functions: To find the composition of functions $(g \circ h)(x)$ , we need to substitute the function $h(x)$ into the function $g(x)$ . This means we will replace every instance of $x$ in $g(x)$ with the expression that defines $h(x)$ .
Write Functions: First, let's write down the functions $g(x)$ and $h(x)$ for clarity: $\newline$ $g(x) = 9 + \frac{5}{4}x$ $\newline$ $h(x) = 10x - 28$ $\newline$ Now, we will substitute $h(x)$ into $g(x)$ .
Distribute and Simplify: Substitute $h(x)$ into $g(x)$ :
$(g@h)(x) = g(h(x)) = 9 + \left(\frac{5}{4}\right)(h(x))$
Now, replace $h(x)$ with its expression:
$(g@h)(x) = 9 + \left(\frac{5}{4}\right)(10x - 28)$
Combine Terms: Next, distribute the $(5/4)$ across the terms in the parentheses: $(g@h)(x) = 9 + \frac{5}{4}\cdot 10x - \frac{5}{4}\cdot 28$
Combine Terms: Next, distribute the $(5/4)$ across the terms in the parentheses: $\newline$ $(g@h)(x) = 9 + (5/4)\cdot 10x - (5/4)\cdot 28$ Simplify the expression by multiplying the constants: $\newline$ $(g@h)(x) = 9 + (50/4)x - (140/4)$ $\newline$ $(g@h)(x) = 9 + (50/4)x - 35$
Combine Terms: Next, distribute the $(5/4)$ across the terms in the parentheses: $\newline$ $(g@h)(x) = 9 + (5/4)\cdot 10x - (5/4)\cdot 28$ Simplify the expression by multiplying the constants: $\newline$ $(g@h)(x) = 9 + (50/4)x - (140/4)$ $\newline$ $(g@h)(x) = 9 + (50/4)x - 35$ Combine the constant terms: $\newline$ $(g@h)(x) = 9 - 35 + (50/4)x$ $\newline$ $(g@h)(x) = -26 + (50/4)x$
