Question

Use the symbolic form of the gas cost of fill-up function,, to evaluate

Answer 1

Answer:

0, $12.40, $24.79, $37.19, $49.58

0 ≤ f(g) ≤ 49.58

Step-by-step explanation:

The cost of fill up gas, f(g) as a function of number of gallons of gas needed (g) is given by f(g) = 2.479g ........(1)

So, f(0) = $0

f(5) = 2.479 × 5 = $12.40

f(10) = 2.479 × 10 = $24.79

f(15) = 2.479 × 15 = $37.19

and f(20) = 2.479 × 20 = $49.58

And the practical range of this function is 0 ≤ f(g) ≤ 49.58

Therefore, option D is correct. (Answer)
