The graph of the piecewise function f(x) is shown.

on a coordinate plane, a piecewise function has 2 lines that connect. the first line is horizontal to the y-axis at y = 4 and goes to (0, 4). the second line goes from (0, 4) through (4, 0).

there is nothing below so i cannot

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.
