Answer:
- decay
- decay
- growth
Step-by-step explanation:
If the base of a positive exponential is greater than 1, the function is a growth function. If it is less than 1, the function decays.
Remember that a^-1 = 1/a, so a negative exponential can be transformed to a positive one.
__
1. y = 2(11/5)^-x = 2(5/11)^x . . . . 5/11 < 1, so decay
2. y = e^(-2x) = (1/e^2)^x . . . . 1/e^2 < 1, so decay
3. y = 1/4e^x . . . . e > 1, so growth
_____
e ≈ 2.71828 . . . an irrational number
Answer:
-13x+10
Step-by-step explanation:
(4x+5)(x-2)
Multiply each term in the first parenthesis by each term in the second (foil)
Step 1: Expand it by writing out each multiplication. I added a picture showing which order to do it. (go in order of green, red, blue, yellow.) (you can remember this as first, outside, inside, last.)
When you expand it'll look like: 4x⋅x+4x⋅-2-5x-5⋅-2
Step 2: Calculate product
4x⋅x+4x⋅-2-5x-5⋅-2 (for the 4x⋅x it would be written like )
+4x⋅-2-5x-5⋅-2
+4x⋅-2-5x-5⋅-2 (4x⋅-2 becomes -8x) (multiply 4x times -2)
-8x-5x-5⋅-2
-8x-5x-5⋅-2 (-5⋅-2 becomes +10) (multiply -5 times -2)
-8x-5x+10
Step 3: collect like terms
-8x-5x+10 (-8x-5x becomes -13x) (-8x times -5x)
-13x+10 is the most simplified so it should be your final answer
