How to identify domain and range from co-ordinate pair.

Now g(-2)=0

5

Step-by-step explanation:

First you want to find f(-2)

Then whatever f(-2) equal, you plug into g(x) to find g(f(-2))

So first lets find f(-2)

Looking at the f(x) graph. When -2 is inputted ( x value -2 ) the output is 1

So f(-2) = 1

We then plug in 1 into g(x) to find g(f(-2))

Think of it as 1 replacing f(-2) in g(f(-2)) because f(-2) = 1

So g(f(-2)) = g(1)

We then look at the graph g(x)

when 1 is inputted the output is 5

Therefore g(f(-2)) = 5

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
