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.
