Problem : Simplify the following expression: 3(x + 2).

3(x + 2) = 3x×32 = 9×3x.

Problem : What is y-intercept of the graph of the function b×ax?

The y-intercept is at (0, b).

Problem : For what values of x is the function f (x) = 2×2x less than 1?

f (x) < 1forallx < - 1.

Problem : Where do the graphs of y = axandy = a-x intersect?

They intersect at the point (0, 1).

Problem : Does the function f (x) = ()x increase or decrease as x increases or decreases? How about the function f (x) = 3x?

f (x) = ()x increases as x decreases and decreases as x increases. f (x) = 3x decreases as x decreases and increases as x increases.
