Answer:
A (top left)
Step-by-step explanation:
Assuming that the dot is multiplying the numbers, we get the function:
[tex]f(x) = 8^{x}[/tex]
First, lets knock off the obviously wrong answers.
Substitute 0 into the x spot, as anything to the power of zero is one.
[tex]f(0) = 8^{0}=1[/tex]
Automatically, the two answers on the right are incorrect, as y is not equal to 1 when x is 0.
Next, lets substitute 1 into the x spot, as anything to the power of one is itself.
[tex]f(1) = 8^{1} = 8[/tex]
As a result, the top left graph is correct, as y is equal to 8 when x is 1, unlike the bottom left graph.
