Answer:
Thus, the 2nd or lower graph represents the graph of
.
The correct graph is also attached below.
Explanation:
Given the function
![y\:=\:4^x](https://img.qammunity.org/2021/formulas/mathematics/high-school/917vu5ub945iy60k1wxgwayzb0lh7txs28.png)
Let us determine the y-intercept by setting x=0, and then determining the corresponding y-value.
now substituting x = 0 in the function
![y=\:4^0\:](https://img.qammunity.org/2021/formulas/mathematics/high-school/jh5i2mw4hyurc6h1qc3x3l0ka34im9d6ev.png)
Apply the rule:
![a^0=1,\:a\\e \:0](https://img.qammunity.org/2021/formulas/mathematics/high-school/lq41qvzewqog15k3240a886pk5lkc4vne0.png)
![y = 1](https://img.qammunity.org/2021/formulas/mathematics/middle-school/d21pbwd072n5znn1nphqb0yjrrll2y5nzt.png)
Thus, the y-intercept is (0, 1)
Now, if we closely observe the 2nd graph or lower graph, the y-intercept of the lower graph is (0, 1)
Thus, the 2nd or lower graph represents the graph of
.
