This Graph Could Be Which Exponential Function?

The graph below could be which exponential function?





A. F(x) = -4(1.1)5x


B. F(x) = 1.1(4)x


C. F(x) = 4(1.1)5x


D. F(x) = 4(1.1)-x

Figure it out by going to MathPapa.com and comparing graphs. Input your various options:

F(x) = 4(1.1)^(5x). Well what do you know?

The answer looks like C to me...what do you think?;)
