Without graphing, determine whether the function represents exponential growth or exponential decay. then find the y-intercept. f(x)=3(0.59)^x

Hello from MrBillDoesMath!

exponential growth , y-intercept 3

Discussion:

Any equation of the form   b^x          (b a constant) models exponential growth.

The y-intercept value is the value of y when x = 0, that is,

y = 3 (0.59)^0 = 3 * 1 = 3

Thank you,

y-intercept 3

Step-by-step explanation:

$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)
