Joanne drives a tour bus in Hollywood that can hold up to 10 passengers. She charges each passenger $15 dollars to ride. What is a reasonable range for this scenario (see graph at right)?
0,1,2,3,4,5,6,7,8,9,10
0,15,30,45,60,75,90,105,120,135,150 0≤x≤10
1,15,2,30,3,45,4,60,5,75,6,90
The reasonable range for this scenario is $0 to $150.
The total cost in dollars to buy uniforms for the players on a volleyball team can be found using the function
c = 30.75u + 5.75, where u is the number of uniforms bought. If there are at least 8 players but not more than 12 players on the volleyball team, what is the domain of the function for this situation?
0 < u ≤ 12 0<c≤374.75
8, 9, 10, 11, 12
251.75, 282.50, 313.25, 344, 374.74
The correct domain for the function in this situation is 8 ≤ u ≤ 12.
So, the correct domain for this function is 8, 9, 10, 11, 12.
What is the value of f(-2)?
I'm sorry, but without the given function f(x), I cannot calculate the value of f(-2). Please provide the function f(x) so that I can assist you further.
What is the value of f(-2)?
F(x)=10-4x
To find the value of f(-2) using the given function f(x) = 10 - 4x, we substitute -2 for x:
f(-2) = 10 - 4(-2)
= 10 + 8
= 18
Therefore, the value of f(-2) is 18.
