Question

What is the equation of the following graph?theOA. f(x) = 3(2^x)OB. f(x) = 4(1)Oc. f(x) = 2(3*)D. f(x) = 5(2)

Answer 1

To find the answer We can take an x value of zero and then We will see which of the equations is the correct one:

Using the A equation:

`f(0)=3*2^0=3*1=3`

Using the B equation:

`f(0)=4*(1)/(2)^0=4*1=4`

Using the C equation:

`f(0)=2*3^0=2*1=2`

Using the D equation:

`f(0)=5*2^0=5*1=5`

If we look at the graph, for a value of x equal to zero, the function is 3, i.e. y = 3, and the correct answer is A.
