Robert is a stuntman planning to jump off a bicycle ramp and over an array of trucks. He identified a few quantitative relationships and modeled them:
Function
S
Input
Height of the ramp. r
Speed at the edge of the ramp, k
Distance of the jump, ir
D
Output
Speed at the edge of the ramp, S(r)
Distance of the jump, D(k)
Number of trucks Robert can jump over, T(3)
T
The expression S(T(2)) represents which of the following?
Choose 1
The speed at the edge of the ramp as a function of the distance of the jump.
The number of trucks Robert can jump over as a function of his speed at the edge of the ramp.
The distance of the jump as a function of his speed at the edge of the ramp.
None of the above, since S(T(x)) is meaningless.
