f (x) = 26 (2)^{x} + 4 (2)^{x}

The function

f

is defined by the given equation. Which of the following equivalent forms of

f

displays, as a coefficient or a base, the

y

-coordinate of the

y

-intercept of the graph of

y = f (x)

in the

x y

-plane?

f (x) = 104 (2)^{x - 2} + 16 (2)^{x - 2}

f (x) = 2 (13 (2)^{x} + 2 (2)^{x})

f (x) = 26 (4)^{\frac{x}{2}} + 4 (4)^{\frac{x}{2}}

f (x) = 30 (2)^{x}
