Answer:
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.
[tex]f(x)=\sqrt{x}[/tex]
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.
[tex]f(x)=x^3[/tex]
False
Graph 3: It is exponential graph because range is all positive real number and domain is all real number.
[tex]f(x)=3^x[/tex]
True
Graph 4: It is rational function graph because here we have vertical asymptote (x=-2)
[tex]f(x)=\dfrac{1}{x+2}[/tex]
False
