I think the answer is “C” too. See if this pic could help you understand.
Answer:
1. B. a=14, b=2
2. D. a=1, b=1.4
Step-by-step explanation:
The exponential growth function can be represented as
![y=a\cdot b^x,](https://tex.z-dn.net/?f=y%3Da%5Ccdot%20b%5Ex%2C)
where b is the growth factor.
1. When the function has equation
![g(x)=14\cdot 2^x,](https://tex.z-dn.net/?f=g%28x%29%3D14%5Ccdot%202%5Ex%2C)
then
![a=14,\\ \\b=2](https://tex.z-dn.net/?f=a%3D14%2C%5C%5C%20%5C%5Cb%3D2)
The initial amount is the value of the function at x=0:
![g(0)=14\cdot 2^0=14\cdot 1=14](https://tex.z-dn.net/?f=g%280%29%3D14%5Ccdot%202%5E0%3D14%5Ccdot%201%3D14)
The growth factor is b=2
2. When the function has equation
![f(t)=1.4^t,](https://tex.z-dn.net/?f=f%28t%29%3D1.4%5Et%2C)
then
![a=1,\\ \\b=1.4](https://tex.z-dn.net/?f=a%3D1%2C%5C%5C%20%5C%5Cb%3D1.4)
The initial amount is the value of the function at t=0:
![f(0)=1.4^0=1](https://tex.z-dn.net/?f=f%280%29%3D1.4%5E0%3D1)
The growth factor is b=1.4
The range of the function c = 50t + 200 is given by [200, ∞).
<h3>What is a
linear equation?</h3>
A linear equation is in the form:
y = mx + b
Where y, x are variables, m is the rate of change and b is the y intercept.
Let c represent the distance travelled in t hours, hence:
c = 50t + 200
The range of the function c = 50t + 200 is given by [200, ∞).

Answer:
A
Step-by-step explanation:
Slope intercept form is y = mx + b
First find the slope or m with this equation
(plug in)
=
= ![\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D)
So your slope is ![\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D)
To find the y-intercept you use y= mx + b and plug in.
6 = 1/4(12) + b
6 = 3 + b (minus 3 on both sides)
3 = b
so 3 is the y-intercept
So the answer is A.
