Question

1. the graph of $y=2^x$ is displayed here.

1a what is the $y$-intercept of this graph?
$y = 1$

Explanation:

Step1: Define y-intercept condition

The y-intercept occurs at $x=0$.

Step2: Substitute x=0 into the function

$y = 2^{0}$

Step3: Evaluate the exponential expression

$2^{0} = 1$

Answer:

$y=1$
