Question

Keenan buys an embroidery machine for $1,400. He uses it to embroider T-shirts. His total profit in dollars from selling the T-shirts is represented with the function f(x) = 12x − 1,400. When the machine breaks, he pays $135 to have it fixed. How does that cost affect a graph of Keenan’s profit function?

A. The graph is translated up 135 units.

B. The graph is translated down 135 units.

C. The graph is translated left 135 units.

D. The graph is translated right 135 units

Answer 1

The cost of fixing the machine is a decrease in Keenan's profit, which means that the graph of his profit function is shifted down by $135.

Therefore, the correct answer is (B) The graph is translated down 135 units.
