Answer:
one
Step-by-step explanation:
Where the two functions intersect
Answer:
- y = -3 (x ≤ -2)
- y = 2x - 3 (-2 < x ≤ 2)
- y = 5 (2 < x)
Step-by-step explanation:
The leftmost piece of the function is constant at -3.
The middle piece is a line with a slope of 2 that intersects the y-axis at -3, so has equation y = 2x-3. (The slope-intercept form of the equation of a line is y = slope·x + y-intercept. The slope is found by counting the number of vertical grid squares that correspond to each horizontal grid square.)
The rightmost piece is constant at +5.

We don't know what your choices are, so we can't tell you which to select.
Answer:
364ways
Step-by-step explanation
This is a problem on combination. Combination has to do with selection. For example if r objects are to be selected from a pool of n objects, this can be done in nCr ways.
nCr = n!/(n-r)!r!
If a brand has 14brands of hot sauce and he is to pick 3 to mix into a gumbo, he can select those 3 from a pool of 14brands in 14C3 number of ways.
14C3 = 14!/(14-3)!3!
14C3 = 14!/11!3!
14C3 = 14×13×12×11!/11!×6
14C3 = 14×13×12/6
14C3 = 14×26
14C3 = 364ways
