Let $f(x)=-3 x+2, g(x)=\frac{x}{5}, h(x)=-2 x^2+9$, and $j(x)=5-x$. Find each value or expression for #7-#15.

7. $(g \circ f)(x)$

8. $f(x)+j(x)$

9. $f(x)-h(x)$

10. $(g \cdot j)(x)$

11. $(f \circ g)(-2)$.

12. $3 f(x)$

1 h o u r : $8 , 50 2 h o u r : $13 , 64 $13 , 64 − $8 , 50 = $5 , 14 3 h o u r : $18 , 80 $18 , 80 − $13 , 64 = $5 , 16 4 h o u r : $23 , 95 $23 , 95 − $18 , 80 = $5 , 15 5 h o u r : $23 , 95 + $5 , 14 = $29 , 09 6 h o u r : $29 , 09 + $5 , 16 = $34 , 25

I am assuming your $13.64 is supposed to be $13.65. If that is the case. First hour is $8.50 and each additional hour is $5.15 more. Adding 2 hours is $10.30.
23.95+10.30=34.25

The cost for Nate to rent a bicycle for 6 hours is $34.25. This is determined by observing the pattern of increasing costs per additional hour. The calculations indicate that each hour costs roughly an additional $5.15.
