Answer 1

Answer:
`\begin{gathered} a)\text{ y-intercept is at \lparen0, 2\rparen} \\ graph\text{ approaches 0 as x increases \lparen3rd option\rparen} \\ \\ b)\text{ y-intercept is at \lparen0, 1\rparen} \\ graph\text{ approaches positive infinity as x increases \lparen last option\rparen} \end{gathered}`

Step-by-step explanation:

Given:

`\begin{gathered} y\text{ = 2\lparen}(1)/(2))^x \\ y\text{ = 3}^x \end{gathered}`

To find:

to match each given function with its description

`\begin{gathered} y\text{ = 2\lparen}(1)/(2))^x \\ The\text{ y-intercept is at y = 2} \\ The\text{ y-intercept is the value of y when x = 0} \\ In\text{ ordered form, the y-intercept \lparen x, y\rparen: \lparen0, 2\rparen} \\ \\ Graph\text{ approaches 0 as x increases} \end{gathered}`

`\begin{gathered} y\text{ = 3}^x \\ y\text{ intercept is at y = 1} \\ The\text{ y-intercept in orderd form \lparen x, y\rparen: \lparen0, 1\rparen} \\ \\ As\text{ x increases, graph approaches positive infinity} \end{gathered}`
