Sorry got it wrong I didn't know if you had to subtract:>
Answer:
the top right is the only function
Step-by-step explanation:
a function is defined as any set of points for which one x value only has one y value
Plug the x-values from the table into the given equation and solve for y.
y = 5 - x²
<u>First column</u>
replace x with -2
y = 5 - (-2)²
= 5 - (4)
= 1
(x, y) = (-2, 1)
<u>Second column</u>
replace x with -1
y = 5 - (-1)²
= 5 - (1)
= 4
(x, y) = (-1, 4)
<u>Third column</u>
replace x with 0
y = 5 - (0)²
= 5 - (0)
= 5
(x, y) = (0, 5)
<u>Fourth column</u>
replace x with 1
y = 5 - (1)²
= 5 - (1)
= 4
(x, y) = (1, 4)
<u>Fifth column</u>
replace x with 2
y = 5 - (2)²
= 5 - (4)
= 1
(x, y) = (2, 1)
-z = 80
You cannot submit an equation with a negative letter ( -z ) so we have to cancel the negative.
To cancel negatives in the equation, we multiply both sides by -1.
-z * -1 = 80 * -1
z = -80
Answer: z = -80
<h3>
Answer: (4, -1)</h3>
Reason:
When rotating a point 180 degrees around the origin, you use the rule
We flip the sign of each coordinate from positive to negative or vice versa.
The point X is at the location (-4, 1). Rotating this 180 degrees will get us to X'(4, -1)
