omeli [17]2 years ago
5 0

The function f(x) = -5x³ + 3x² + x - 9 is a cubic function with the form:

f(x) = ax³ + bx² + cx + d, where a = -5, dictates the end behavoir of the function.

Since a is negative, then as x → -∞, y → ∞, and as x → ∞, y → -∞.

Math problem: intervals
IRISSAK [1]

Answer:

B

Step-by-step explanation:

Given the function h(t)=(t+3)^2+5.

Find the average rate of change on interval [t_1,t_2]:

\dfrac{h(t_2)-h(t_1)}{t_2-t_1}=\\ \\=\dfrac{((t_2+3)^2+5)-((t_1+3)^2+5)}{t_2-t_1}=\\ \\=\dfrac{(t_2^2+6t_2+9+5)-(t_1^2+6t_1+9+5)}{t_2-t_1}=\\ \\=\dfrac{t_2^2-t_1^2+6t_2-6t_1}{t_2-t_1}=\\ \\=\dfrac{(t_2-t_1)(t_2+t_1)+6(t_2-t_1)}{t_2-t_1}=\\ \\=\dfrac{(t_2-t_1)(t_2+t_1+6)}{t_2-t_1}=\\ \\=t_2+t_1+6

This value is negative only for t_1=-4,\ t_2=-3, so correct option is B
