To get the inverse
of any function f(x) [ just make sure that it passes the horizontal line test]
follow the steps:
- Solve for x, i.e separate x in one side
and the other terms in the other side, included f(x).
- Swap x and f(x).
- The result is the inverse of the original
function
.
-------------------------
Apply that on your function
It is c.
explanation:
20+130+h =180
when you solve you get h=50
130+g = 180
g= 50
50+60+f = 180
f=70

Answer:
plastic = 45
metal = 30
Step-by-step explanation:
X=20. Because that line is 180 and u subtract 40 and u do 140/7= 20
