Shannon saves 1235 in november. In november, she saved $250 less than she did in december. How much money did she save in the tw

madam [21]

In December she would have saved $1585 because 1235 + 250 = 1485. You can find how much money she raised in those 2 months by adding the totals of both months together, so 1485 + 1235 = 2720. She saved $2720 in the 2 months.

Answer:

Step-by-step explanation:

Given a set of elements corresponding to the domain, we obtain the range by evaluating the function at each value:

22. $f(x) = x^{2}-3$

$f(-2) = (-2)^{2}-3$

$f(-2) = 1$

$f(0) = 0^{2}-3$

$f(0) = -3$

$f(2) = 2^{2}-3$

$f(2) = 1$

$f(4) = 4^{2}-3$

$f(4) = 13$

The set of ordered pairs associated with the given function is:

$S = \{(x,y)|(-2,1), (0,-3), (2,1), (4,13)\}$

23. $g(x) = -5\cdot x + 2$

$g(-4) = -5\cdot (-4)+2$

$g(-4) = 22$

$g(-1) = -5\cdot (-1) + 2$

$g(-1) = 7$

$g(3) = -5\cdot (3) +2$

$g(3) = -13$

The set of ordered pairs associated with the given function is:

$S =\{(x,y)|(-4,22),(-1,7),(3,-13)\}$
