Which graph represents an exponential function?

C

Step-by-step explanation:

A) f(x) = √x

B) f(x) = x³

C) f(x) = 2ˣ             x is the exponent so it is an EXPONENTial function

D)  f(x) =

Graph 3 is exponential function.

Step-by-step explanation:

We are given four different graph. We need to choose exponential graph.

Graph 1: It is square root graph because the value of x and y not negative in this graph. Graph is slight curve.

False

Graph 2: It is is cubic graph because it start from bottom of the coordinate plane and end at top of the coordinate plane.

False

Graph 3: It is exponential graph because range is all positive real number and domain is all real number.

True

Graph 4: It is rational function graph because here we have vertical asymptote (x=-2)

False
