Answer:
<h2>H = 3</h2>
Step-by-step explanation:

Answer:
if given f(-x)=x-7, then f(h(x))=-2x-10
or if given f(x)=x-7, then f(h(x))=2x-4
Step-by-step explanation:
if given f(-x)=x-7
f(-x)=x-7 => f(-(-x))=(-x)-7 =>f(x)= -x-7
f(h(x))=f(2x+3)= -(2x+3)-7 = -2x-3-7 = -2x-10
if given f(x)=x-7
f(h(x))=f(2x+3)=2x+3-7=2x-4

Answer: C, a set of coords is only a function if it passes the vertical line test
Step-by-step explanation:
This is essentially the vertical line test. No two sets can have the same x value because it will fail the vertical line test. In answer a, -4 correlates to two y values. It fails the line test
B easily fails the test just by visually looking at it. It fails the line test
C has different x values so this looks promising. It passes the line test
D has the number 5 correlating with multiple y values. It fails the line test
