Answer: third option
Step-by-step explanation:
By definition, for the function
if 0<b<1 then the function decreases from left to right
Therefore, it cannot be the options 1 or the option 2.
As the function given in the third option of problem has a negative coefficient (which is -2) and b=0.3 (0<b<1)
![y=-2*0.3^x](https://tex.z-dn.net/?f=y%3D-2%2A0.3%5Ex)
Then, each ouput value wil be negative.
Therefore, you can conclude that the function
decreases and going downwards from left to right.
The answer is C. because 1/10 + 3/10 = 4/10. 4/10 can be simplified to 2/5
You do 9/10. Which here it only fits once. So this is 1 1/10. The other one fits 3 times. So its 3 1/10.
If you want the subtraction also done its 1 4/10.
Answers:
A) x > 4
B) x ≤ -5
I just answered the first two, but use Tiger Algebra. You can write down and take a picture of your equation, type it, or draw it on the writing pad they provide.
Hope this helps! :3
I'm absolutely certain that the answer is 2. (0,-4), (5,3), (-4,3), (3,2) because in a function, x does not repeat
