The ordered pairs (1,3), (2,9), (3,27), (4,81) and (5,243) represent a function. What is a rule that represents this function?
Y=x^3
Y=3x
y=3^x
y=x+2
OpenStudy (anonymous):
ar u in 6th
OpenStudy (anonymous):
no lol just didn't study this stuff was in the hospital with a broken neck
OpenStudy (anonymous):
y = (x+4)^2

Suppose yogurt is on sale for $0.50 a piece, and you have a coupon for $0.30 off your total purchase. Write a function rule for the cost of n yogurts. How much would 20 yogurts cost?
C(n)=0.5-0.3;$9.70
C(n)=0.3n-0.5;$5.50
C(n)=0.2n;$4.00
C(n)=0.5n;$10.00

cn=0.5-0.3;$9.70

LIsa earns $7.50 per hour mowing lawns
a. Write a rule to describe how the amount of money m earned is a function of the number of hours h spent mowing lawns.
b. How much money does lisa earn if she works for 5 hours and 45 minutes?
m(h)=5h+45;$37.95
m(h)=7.50h;$40.88
m(h)=h/7.50;$1.30
m(h)=7.50h;$43.13

My wrist hurts now from typing that out lol

this is a snap
m(h)=7.5(h)
OpenStudy (anonymous):
So, I think you mean m(h)=7.50h;43.13

A magician charges $50.00 for a visit and an additional $7.50 for each hour he performs. The function rule C=7.50h+50.00 describes the relationship between the number of hours h and the total cost of the visit C. If the magician will only visit a maxiumum of 8 hours, what is a reasonable graph of the function rule?
