Question

The graph of an exponential function is given. Select the function for the graph from the following options:

f(x) = 4x,

g(x) = 4-x,

h(x) = -4-x,

r(x) = -4-x + 3,

Expert Solution
Step 1

Consider the functions :

f(x)=4x, g(x)=-4-x, h(x)=-4-x and r(x)=-4-x+3.

In the graph observe that function passes through the point (0,2).

Check the function which passes through this point.

For f(x)=4x, g(x)=4-x  and h(x)=-4-x when x=0.

f(0)=1, g(0)=1  and h(0)=-1.

None of the three function passes through the point (0,2).
