Question

the figure shows the cost of mailing a first - class letter, f(x), as a function of its weight, x, in ounces, for weights not exceeding 3.5 ounces. find f(0.75). what does this mean in terms of the variables in this situation? f(0.75)=□ what does this mean in terms of the variables in this situation? it costs $□ to mail a □ - ounce first - class letter

Explanation:

Step1: Locate x - value on graph

Locate \(x = 0.75\) on the x - axis (weight in ounces).

Step2: Find corresponding y - value

Move vertically up from \(x = 0.75\) until reaching the graph of the function, then move horizontally to the y - axis (cost in dollars). The corresponding y - value is \(0.58\).

Answer:

\(f(0.75)=0.58\)
It costs $\$0.58$ to mail a \(0.75\) - ounce first - class letter.
