Given : y = 8 - 9x
(a) we need to find value of y when x = 2
substituting x = 2 in y = 8 -9x , we get :
y = 8 - 9(2)
y = 8 - 18
y = -10
(b) we need to find value of y when x = 0
substituting x = 0 in y = 8 -9x , we get :
y = 8 - 9(0)
y = 8 - 0
y = 8
Hey there! :)
Answer:
First option: As x⇒ ∞ f(x) ⇒ -∞. As x⇒ -∞ f(x) ⇒ ∞.
Step-by-step explanation:
Rearrange the equation:
f(x) = -x³ - 2x² + 1
This is a negative cubic function. The function decreases over the interval
(-∞, ∞). Therefore:
As x⇒ ∞ f(x) ⇒ -∞.
As x⇒ -∞ f(x) ⇒ ∞.
This is the first option.
Theres about 800 different combinations, i'm not sure though, i'm sorry if i'm wrong
