Answer:
D{(0, 0), (-1, -0.5), (-2, -1), (-3, -1.5), (-4, -2)}
Step-by-step explanation:
A function is a relation in which we take every element of the first group and assign an unique element of the second group.
So, the set of ordered pairs that represents y as a function of x is the set that take every value of x and assign an unique value of y.
Then, the set A is not a function because we have the ordered pairs (3,9) and (3,16) in which we have two values of y for the value of x=3.
At the same way, we can said that B and C aren't functions.
Finally, D is the set of ordered pairs that represents y as a function of x because every x has an unique value of y.
Answer:
Step-by-step explanation:
A parabola has the following format:
If a is positive, it's minium value is:
In which
Factoring:
, in which 
are the intercepts.
In this question:
So
Suppose a = 1, we have:
The minimum value will be:
We want this minimum value to be -4, which is 4 times the current minimum value, so we need to multiply a by 4. Then
And the parabola is:
An independent variable doesn’t have to rely on another variable. A dependent variable relies on the variable of another, and will change depending on it.
Answer: Y-intercept:(0,3)
x-intercept:(-1.5,0)
Step-by-step explanation:
14 divided by 20 is 0.7
Multiply that by 100
The answer is 70%
