Function or not function?

not function

Step-by-step explanation:

Not function

Step-by-step explanation: In mathematics, the vertical line test is a visual way to determine if a curve is a graph of a function or not. If a vertical line intersects a curve on an xy-plane more than once then for one value of x the curve has more than one value of y, and so, the curve does not represent a function.

$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)

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
