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:

$\begin{gathered} 10=2\cdot b^1 \\ \frac{10}{2}=b \\ 5=b \end{gathered}$

Therefore, the function is:

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