Question

Which of the following exponential equations could describe the graph shown below

Answer 1

Since the line crosses the Y axis below 1 and raises going to the right it would be y=1/3(4)^x

Answer 2

Answer:

3. $y=\frac{1}{4}(\frac{1}{2} )^{x}$

Step-by-step explanation:

To find the equation best suited to the graph, look at the y-intercept, which is where x = 0 and y = $\frac{1}{4}$. Use each formula and replace the x with zero to determine the y-intercept of each formula:

1) $y=2(5)^{0} =2$

2)$y=\frac{1}{3}(4)^{x0}=\frac{1}{3}$

3)$y=\frac{1}{4} (\frac{1}{2} )^{0} =\frac{1}{4}$

4)$y=5(\frac{1}{4})^{0}=5$

The only likely equation is number 3
