Answer:
Step-by-step explanation:
Domain is the set of all possible inputs (x) for the function f(x)
The range is the set of all possible values for that domain
This function is 4x + y = 3 which can be re-written as y = 3-4x
Plug in each of the domain values and you will get the range
For -2 : y = 3-4(-2) = 3 + 8 = 11
For 1: y = 3-4(1) = -1
For 5: y = 3-4(5) = -17
So range is {-17, -1, 11}
9514 1404 393
Answer:
y = -x + 5/2
Step-by-step explanation:
The 2-point form of the equation of a line can be useful.
y = (y2 -y1)/(x2 -x1)/(x -x1) +y1
y = (-2.5 -11)/(5 -(-8.5))/(x -(-8.5)) + 11
y = -13.5/13.5(x +8.5) +11 . . . . . . simplify a bit
y = -x +2.5 . . . . . write in slope-intercept form
Add 3 to both sides of the equation :<span>
</span> y = 3
It is the commutative property since you can switch 5 and 4 around but still get the same answer (9).
