Question

Which exponential function is represented by thegraph?f(x) = 2(34)f(x) = 3(3*)f(x) = 3(2x)O f(x) = 2(2)

Answer 1

The graph of function passes through points (1,6), (0,3) and (-1,1.5).

Determine the function that satify all the points.

For point (1,6)

$\begin{gathered} f(1)=2(3^1) \\ =2\cdot3 \\ =6 \end{gathered}$

Function satisy the point.

For point (0,3);

$\begin{gathered} f(0)=2(3^0) \\ =2\cdot1 \\ =2 \end{gathered}$

Function not satify the points.

Check for the scond function.

For point (1,6);
