Question

Which is the graph of f(x)=2(3)^x

Answer 1

Answer-

The first graph represents $f(x)=2(3)^x$

Solution-

The given function is,

$f(x)=2(3)^x$

Putting x = 1,

$f(x)=2(3)^1=2(3)=6$

So, the point (x, f(x)) i.e (1, 6) must satisfy or lie on the curve of the function.

Only in case of the first graph, the point (1, 6) lies on the curve.

Therefore, the first graph represents the function $f(x)=2(3)^x$ correctly.
