What is the value of f(15) for the given function? what does this value mean in the context of the situation you described in part a?

f(15) is the area of the rectangular garden for a width of 15 ft

Step-by-step explanation:

we know that

where

x----> is the width of the rectangular garden

(2x+5) ----> is the length of the rectangular garden

so

f(15) -----> is the value of f(x) for x=15 ft

That means

f(15) is the area of the rectangular garden for a width of 15 ft

substitute the value of x and solve

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
