Write the cubic polynomial function f(x)in expanded form with zeros −5,−2,and −1, given that f(-3)=4 f(x) =

13.46

step-by-step explanation:

16.80 x .20 = 13.46

15.36 per mile

but forgot to round

i am pretty sure

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
