The table below shows the fourth roots of different numbers:

number (x) 1 1 81 81
fourth root of the number (y) 1 −1 3 −3

part a: does the table represent y as a function of x? justify your answer. (5 points)

part b: the total cost f(x), in dollars, for renting a truck for x hours is shown below:

f(x) = 25x + 16

what is the value of f(20) and what does f(20) represent? (5 points)

lol we need to see what the question is asking about

step-by-step explanation:

in 1995, potato plants were taken into space aboard the space shuttle columbia.

step-by-step explanation:

c = 0.429t

step-by-step explanation:

the constant rate at which carlos harvests cassava is 35 minutes per 15 cassavas 15/35 = 0.429 cassava per minute

therefore, an equation that models the number of cassava (c) that harvest carlos in a time (t) is the following:

where t is the time in minutes.

this means that when 35 minutes have elapsed 15 cassava have been harvested, at 70 minutes 30 cassava have been harvested and so on.
