Practice Test 7

Function $f$ is given algebraically by $f(x)=2x-3$. Function $g$ is given in the table.

Which function has the larger y-intercept?

Table for $g(x)$:

• when $x=0$, $g(x)=1$
• when $x=2$, $g(x)=5$

Function $f$ is given by $f(x)=5-2x$.

Function $g$ is given in the table.

At $x=3$, which function has the greater output?

Table for $g(x)$:

• $g(1)=2$
• $g(2)=1$
• $g(3)=0$
• $g(4)=-1$
