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:
Step-by-step explanation:
So you have the equation:
. As you may know, you cannot divide by 0, so y has to be restricted in a way that the denominator is never equal to 0. So to find when y makes the denominator 0, simply set the denominator equal to 0, and solve for y. This gives you the equation: 5+y = 0, y=-5. So the y value CANNOT be equal to -5. Because it makes the denominator 0. so would be the restriction.

Answer:
x>1
Step-by-step explanation:
move the constant to the right side and change its sign 7x>10-3
Then subtract the numbers 7x>7
Then divide the inequality by 7 from for both sides.
x>1
Answer:
Approximately 775,000.
Step-by-step explanation:
