Answer:
A
Step-by-step explanation:
f(x) = 2x^2 – 3x + 1 is a function (its graph is a parabola that opens up), and it is one-to-one (Answer A). For each input, x, this function will return one output.
The answer is 1 and 1/12 because you have to have a common denomonator.
X+2 is the only command factor when re-writing the expression in Alternate form.
(x+8) (x+2) & (x+9) (x+2)
Shifted up
For example: if f(x) = x^2 + 4, the parent function has a vertex at (0,0), but the +4 shifts the graph up 4 units on the y-axis so the vertex would be (0,4)
Answer:
See below ~
Step-by-step explanation:
<u>Q1</u>
- y = (x + 3i)(x - 7)
- y = x² + 3ix - 7x - 21
- <u>y = x² + (3i - 7)x - 21</u>
<u>Q2</u>
- y = (x - √5)(x - i)
- y = x² - √5x - ix + √5i
- <u>y = x² - (√5 + i)x + √5i</u>
