What is a function that matches the description?
A Sinusoidal Function has a y-intercept at 4, midline y=4, and maximum value of 8 and completes 4 cycles of the interval [0,2π]

Option 1

Step-by-step explanation:

f(x) = Asin(Bx) + C

C = 4

B = 4

A = 8-4 = 4

f(x) = 4sin(4x) + 4

answer: 5100 just subtract

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
