if (h(x)=5 + x) and (k(x)=\frac{1}{x}), which expression is equivalent to ((kcirc h)(x))?\n(\frac{(5 + x)}{x})\n(\frac{1}{(5 + x)})\n(5+left(\frac{1}{x}\right))\n(5+(5 + x))
Answer
Explanation:
Step1: Recall composition of functions
The composition ((k\circ h)(x)=k(h(x))).
Step2: Substitute (h(x)) into (k(x))
Given (h(x)=5 + x) and (k(x)=\frac{1}{x}), we substitute (h(x)) into (k(x)). So (k(h(x))=\frac{1}{h(x)}).
Step3: Replace (h(x)) with its expression
Since (h(x)=5 + x), then (k(h(x))=\frac{1}{5 + x}).
Answer:
(\frac{1}{(5 + x)})
