Answer:
The table is a quadratic function
Step-by-step explanation:
Given
The attached table
Required
Tell if it is a quadratic function
The difference in the x values are uniform (i.e. difference of 1), so the following method can be applied.
(1) Subtract adjacent y values.
(2) Subtract adjacent differences in (1) above
Notice the calculated differences in (2) are the same.
<em>Hence, the table is a quadratic function</em>
Answer:
y=-2x+3
Step-by-step explanation:
y=mx+b
m=-2,b=3
so, y=-2x+3
hopes this helps
Answer:
The answer is D.
Step-by-step explanation:
This is because the first part of the expression is the conjugate and youre given -5. The second part of the expression is the imaginary part and youre given 4i.
IQR = Q3 - Q1 = 92 - 72 = 20
20 * 1.5 = 30
72 - 30 = 42....outlier is anything below 42
92 + 30 = 122...outlier is anything above 122
so the outlier is 41
Answer:
yes, no, yes, no
Step-by-step explanation:
For it to be a line, that means that when x goes up by 1 y goes up by the same thing every time.
7a. from (1, 12) to (2, 8), the x coordinate goes up by 1 and the y coordinate goes down by 4. From (2, 8) to (3, 4) the y coordinate again goes down by 4 when the x coordinate goes up by 1. This pattern continues for the other points, so yes.
Do the same thing for the rest and you should get:
7b. No
7c. Yes
7d. No
