An expression that can only provide a single solution, y,
for any given input, x, is called a “function”.
The given pairs are in the form (x,y)
Looking at set A:
(4,-2), (-2, 2), (2,-2), (4, 2)
Notice that if x=2, there are 2 y’s, -2 and 2. Therefore this
set is not a function.
<span>Answer: A is not a
function</span>
Answer:
(5,7,8.6)
Step-by-step explanation:
Create a line on each the x axis and the y axis which intersects at a right triangle. The x axis line is 7 squares and the y axis is 5 squares. Now you can use the Pythagorean theorem.
a^2+b^2=c^2
7^2+5^2=c^2
49+25=c^2
74=c^2
8.6=c
