Question 4
Laura rents a movie for a flat fee of $2.00 plus an additional $0.50 for each night she keeps the movie. Choose the cost function that represents this scenario if x equals the number of nights Laura has the movie.

c(x) = 2.00x + 0.50

c(x) = 2.00 + 0.50x

c(x) = 2.50x

c(x) = (2.00 + 0.50)x

Question 5
If g(x) = 2(x − 4), find the value of x if g(x

Answer 1

FOR ques no1 f(x)=-4x-1
=>f(-2)=-4.-2-1
=8-1
=7

Answer 2

f(x) = −4x − 1
f(−2)=-4(-2)-1
f(−2)=8-1
f(−2)=7

h(x) = 2x + 3
9=2x+3
2x=9-3
2x=6
x=6/2
x=3

Answer 3

c(x) = 2.00x + 0.50 means 50 cents flat fee and 2.00 per night

c(x) = 2.50x means 2.50 per night and 0 flat fee

c(x) = (2.00 + 0.50)x means 2.50 per night as well
