In the given figure there are 3 graphs
The line represents a linear function
![h(x)=x+2](https://tex.z-dn.net/?f=h%28x%29%3Dx%2B2)
The parabola represents a quadratic function
![g(x)=2.5x^2+2x](https://tex.z-dn.net/?f=g%28x%29%3D2.5x%5E2%2B2x)
The third graph which approaches to the negative part o the x-xis is the exponential function
![f(x)=2^x](https://tex.z-dn.net/?f=f%28x%29%3D2%5Ex)
The x-intercept of the line is (-2, 0)
x-intercept means intersect the x-axis at point (-2, 0)
There is only one graph that intersects the x-axis at (-2, 0)
It is the line, the linear function h(x)
The range is between 0 to infinity (0, ∞)
The range is the values of y
There is only one graph that has all values of y over the x-xis
it is f(x) the exponential function
Answer:
The answer is 5.
Since he has 3 part chocolate all he has 18 cups left. You can keep adding 3 till you get 18 and how many ever groups you have with 3 (which is 5 groups) is the answer.
Answer:
20% Increase

Answer:
10⁴ seconds
Step-by-step explanation:
Given that,
A person breathes
in about cubic meters of air per second.
We need to find time taken to breathe 2.5 cubic meters of air.
In 1 sec =
m³ of air breathe
Let in x seconds, 2.5 m³ of air taken by the person.
![x=\dfrac{2.5}{2.5\times 10^{-4}}\\\\x=10^4\ s](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B2.5%7D%7B2.5%5Ctimes%2010%5E%7B-4%7D%7D%5C%5C%5C%5Cx%3D10%5E4%5C%20s)
Hence, in 10⁴ seconds 2.5 m³ of air is taken by the person.
