Use the alternating series estimation theorem to estimate the range of values of x for which the given approximation is accurate to within the stated error. (round the answer to three decimal places.) check your answer graphically. arctan (x) aprox x - x^3/3 + x^5/5, (|error| < 0.0005)

step-by-step explanation:

2x + 8

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
