Question

3. A store sells roasted peanuts in 1, 2, 2.5, and 4 pound bags.

The peanuts cost $4 per pound. Write an equation in function
notation that represents the cost of the peanuts in terms of the
number of pounds, and graph the function.

Answer 1

To represent the cost of peanuts in terms of the number of pounds, we can use the function c(x) = 4x. The graph of this function is a straight line with a slope of 4.

Step-by-step explanation:

To write an equation in function notation that represents the cost of the peanuts in terms of the number of pounds, we can use the following steps:

1. Let c(x) represent the cost of peanuts, where x is the number of pounds.
2. Since the peanuts cost $4 per pound, the equation can be written as: c(x) = 4x.

To graph the function, we can plot the number of pounds on the x-axis and the cost on the y-axis. The function c(x) = 4x represents a straight line that passes through the origin (0,0) with a slope of 4.
