Evaluate a^2b^2c^2 for a = 2, b = 3, and c = 4

The expression is telling you to multiply the squares of the three numbers.

So, you simply have to square a, b and c, and then multiply the results:

the range of this function is (-∞, ∞)

Step-by-step explanation:

f(x) = 2(3)x should be written with " ^ " to denote exponentiation:

f(x) = 2(3)^x

To help yourself visualize the range:  

f(-∞) approaches zero as x decreases

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

f(2) = 2(3^2) = 18

As x increases, y increases without bound.

Thus, the range of this function is (-∞, ∞).
