Answer:

- 77x + 42

Step-by-step explanation:

note that (f ○ g)(x) = f(g(x)

Substitute x = g(x) into f(x)

f(g(x))

= f(7x - 4)

= - 11(7x - 4) - 2

= - 77x + 44 - 2

= - 77x + 42

Which statement regarding the function y=sin(x) is true?

REY [17]

<h2>Answer:</h2>

c. Reflection over either the x-axis or y-axis will change the graph

<h2>Step-by-step explanation:</h2><h3>a. Reflection over the y-axis will not change the graph since sine is an even function.</h3>

This is false because $y=sin(x)$ is an odd function, not an even one. This means that $sin(-x)=-sin(x)$ , and a reflection over the y-axis will change the graph.

This is false because we said that $sin(-x)=-sin(x)$

<h3>c. Reflection over either the x-axis or y-axis will change the graph</h3>

This is true. Since $sin(x)$ is an odd function, then reflection over either the x-axis or y-axis will change the graph as we said in a. So, for $f(x)$ :
