A. all real numbers for both
Explanation:
Domain is the x-values. Since the graph goes forever horizontally, any x-value is on the graph.
Range is the same but with y-values. If the graph went on further than what the picture shows, then it also would show that every y value is on the graph
hope this helps
Answer: 28 years
Step-by-step explanation:
Given
The equation showing the value of the bag after x years is ![C=25(1.025)^x](https://tex.z-dn.net/?f=C%3D25%281.025%29%5Ex)
If the price of the bag increased by 2.5%, from the equation, we can deduce that
Initial cost of the bag is 25
Double of the initial value is 50
Insert it in the equation
![\Rightarrow 50=25(1.025)^x\\\Rightarrow 2=1.025^x\\\text{Taking natural log}\\\Rightarrow \ln 2=x\ln (1.025)\\\\\Rightarrow x=\dfrac{\ln 2}{\ln 1.025}\\\\\Rightarrow x=28.07\approx 28](https://tex.z-dn.net/?f=%5CRightarrow%2050%3D25%281.025%29%5Ex%5C%5C%5CRightarrow%202%3D1.025%5Ex%5C%5C%5Ctext%7BTaking%20natural%20log%7D%5C%5C%5CRightarrow%20%5Cln%202%3Dx%5Cln%20%281.025%29%5C%5C%5C%5C%5CRightarrow%20x%3D%5Cdfrac%7B%5Cln%202%7D%7B%5Cln%201.025%7D%5C%5C%5C%5C%5CRightarrow%20x%3D28.07%5Capprox%2028)
It will take 28 years
Answer:idk
Step-by-step explanation:
Answer:
rational
Step-by-step explanation:
In -2x
![x^{2}](https://tex.z-dn.net/?f=%20x%5E%7B2%7D%20)
, the exponent will be dealt with first. With (-2x)
![^{2}](https://tex.z-dn.net/?f=%20%5E%7B2%7D%20)
, the multiplication is going to be done first. This is determined because of Order of operations.
