Question

The graph below could be the graph of which exponential function

Answer 1

The correct answer is C. F(x)=2 * (0.7)^x

Answer 2

`y=2.(0.5)^(x)`

Explanation:

Although the options of this question have not been given, but still we can find the function from its graph.

Let the function is,

`y=a(b)^(x)`

This graph is passing through two points (0, 2) and (1, 1).

By substituting these points in the function we can find the values of a and b,

For (0, 2),

`2=a(b)^(0)`

a = 2

For (1, 1),

`1=2.(b)^(1)`

`b=(1)/(2)`

Therefore, given graph represents an exponential function,

`y=2.((1)/(2))^(x)`

Or,
`y=2.(0.5)^(x)`
