This function f(x) has a domain of x = {-a, -b, a, b}.
in order, the x values are -a, -b, b, a.
in order, the f(x) values are 3c + 1, 2d - 5, 4d + 3, 6 - 2c.
which values of c and d make this an even function?
a. c = -7 and d = 1/3
b. c = 5 and d = 1/3
c. c = -5 and d = -4
d. c = 1 and d = -4
e. c = -7 and d = -4
Answer from: brayden2275
d. c = 1 and d = -4
Step-by-step explanation:
If a function is even, then f(-x) = f(x). Graphically, this means it's symmetrical about the y-axis.
f(-a) = f(a)
3c + 1 = 6 − 2c
5c = 5
c = 1
f(-b) = f(b)
2d − 5 = 4d + 3
-2d = 8
d = -4
Therefore, c = 1 and d = -4.

Evaluate 8x2 + 9x − 1 2x3 + 3x2 − 2x dx. solution since the degree of the numerator is less than the degree of the denominator, we don't need to divide. we factor the denominator as 2x3 + 3x2 − 2x = x(2x2 + 3x − 2) = x(2x − 1)(x + 2). since the denominator has three distinct linear factors, the partial fraction decomposition of the integrand has the form† 8x2 + 9x − 1 x(2x − 1)(x + 2) = correct: your answer is correct. to determine the values of a, b, and c, we multiply both sides of this equation by the product of the denominators, x(2x − 1)(x + 2), obtaining 8x2 + 9x − 1 = a correct: your answer is correct. (x + 2) + bx(x + 2) + cx(2x − 1).
