The absolute value of a quantity is 5 if that quantity is either 5 or -5.
So, the two solutions are
Now, there is a bit of ambiguity here: we are not told who and
are exactly, and yet the value of
depends on our choice.
If we choose a = 2 and b = -3, then the value of a-b is 5
If we choose a = -3 and b = 2, then the value of a-b is -5
Answer:
the last option:
Step-by-step explanation:
Make sure you have the numerical answer for each of the functional expressions that are shown among the possible solution choices:
f(4) = -14 (what the blue function reads [its y-value] when x is 4)
g(4) = 10 (what the red function reads [its y-value] for x=4)
g(-2) = 4 (y-value of the red function when x is -2)
f(2) = -8 (y-value of the blue function for x = 2)
f(-2) = 4 (y-value of the blue function for x =-2)
use them to compare the options they give you, and the only one that matches is the last option.
