Answer:
(x - 2)² - 30
Step-by-step explanation:
To complete the square
add/subtract ( half the coefficient of the x- term )² to x² - 4x
f(x) = x² + 2(- 2)x + 4 - 4 - 26 = (x - 2)² - 30
Answer:
Look that the coordinates and trace those points to a corresponding number on the x or y axis. Then write the first number in the coordinate in the x value and the second number for the y value, repeat the process for the rest of the points.
Step-by-step explanation:
Answer
-1
Step-by-step explanation:
Just plug in the numbers.
Answer:
Question 1:
(3)
x 3 5 7 9
f(x) 2 4 2 4
Question 2:
(2) whole numbers
Step-by-step explanation:
1.
In a function, each x-value must only have 1 y-value, but a y-value can have multiple x-values.
2.
A whole number is any positive number that is not a fraction. You cannot have negative devices nor a fraction of a device.
Answer:
m = 0
Step-by-step explanation:
The denominator of the rational expression cannot be zero as this would make the rational expression undefined. Equating the denominator to zero and solving gives the value that m cannot be.
4m² = 0 ⇒ m² = 0 ⇒ m = 0 ← excluded value
