Answer:
Step-by-step explanation:
We need to remember 2 rules when doing these:
1.
2.
Using these 2 rules, we can simplify the product (steps shown below):
Rearranging, we see that it is the third choice.
Evaluate the function. f(x)= - x^2 - 10x find f(-5)

Answer:
C
Step-by-step explanation:
I think I will answer the question the your attachment because it has full information.
The function is: y = 3*
a. The function decreases
Wrong, because the base number is 2 and it is greater than 0. The function will go up
b. y=intercept of (0.2)
Wrong, Let substitute x =2 into the function: y = 3* = 12
c. if x increase by 1, the value of y will double
Because the base number is 2. For example:
- If x = 2, y = 3*
= 12
- If x =3, y =3*
=(3*
d. contains the point (2,4)
Wrong, Let substitute x =4 into the function: y = 3* = 48
So we choose C
