1. the table below shows the cost of some apples. which function c(a) is represented in the table?
apples
cost
3
$1.95
6
$3.90
9
$5.85
a. c(a) = 0.65a
b. c(a) = 1.95a
c. c(a) = 3a
d. c(a) = 0.85a
2. which function below translates the parent function f(x) = x4 five units to the right and seven units downward?
a. g(x) = (x – 7)4 – 5
b. g(x) = (x – 5)4 + 7
c. g(x) = (x – 5)4 – 7
d. g(x) = (x + 5)4 – 7
3. use the mapping shown to show the value of the function f(x) at each point.
a. f(5) = –1, f(3) = 0, f(5) = 1, f(11) = 2, f(21) = 3
b. f(1) = 5, f(0) = 3, f(1) = 5, f(2) = 11, f(3) = 21
c. f(–1) = 5, f(0) = 3, f(1) = 5, f(2) = 21, f(3) = 11
d. f(–1) = 5, f(0) = 3, f(1) = 5, f(2) = 11, f(3) = 21
