Question

Jojo likes to paint. She estimates the number of paintings she completes using the function P of w equals two thirds times w minus two, where w is the number of weeks she spends painting. The function J(y) represents how many weeks per year she spends painting. Which composite function would represent how many paintings Jojo completes in a year?

Answer 1

Answer:

$P = \frac{2}{3} [J(y)] - 2$

Step-by-step explanation:

If Jojo completes P number of paintings working w weeks then the relation between P and w is given by $P = \frac{2}{3} w - 2$. ........ (1)

Again, the function J(y) represents how many weeks per year she spends painting.

So, w = J(y). ...... (2)

Therefore, the composite function which represent how many paintings Jojo completes in a year, is given by  

$P = \frac{2}{3} [J(y)] - 2$  (Answer)

Answer 2

Answer:

p{j(y)}=2/3*j(y)-2
