Given the function F(x) -2x + 4,
0 -5x + 11, X _>8
is the function increasing or decreasing over
the interval [2, 7]? Find the rate of change
over this interval.

well what did you do it matters what you did : )

step-by-step explanation:

"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
