Question

Is it option one or two I don't need to work

Answer 1

From the options, the function has the next form

`y=a\cdot b^x`

where a and b are two constants.

The function pass through the point (0, 2), then:

`\begin{gathered} 2=a\cdot b^0 \\ 2=a\cdot1 \\ 2=a \end{gathered}`

The function pass through the point (1, 10), then:

`\begin{gathered} 10=2\cdot b^1 \\ (10)/(2)=b \\ 5=b \end{gathered}`

Therefore, the function is:

`y=2\cdot5^x^{}`
