the price of fuel may increase due to demand and decrease due to overproduction. marco is studying the change in the price of two types of fuel, a and b, over time.
the price f(x), in dollars, of fuel a after x months is represented by the function below:
f(x) = 2.15(0.98)^x
part a: is the price of fuel a increasing or decreasing and by what percentage per month? justify your answer. (5 points)
part b: the table below shows the price g(m), in dollars, of fuel b after m months:
m (number of months) 1 2 3 4
g(m) (price in dollars) 4.19 3.98 3.78 3.59
which type of fuel recorded a greater percentage change in price over the previous month? justify your answer.

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).
