For the function below, find ordered pairs for: x = -2 and x = 5 y = 9 - 4x
Answer:
(- 2, 17 ) and (5, - 11 )
Step-by-step explanation:
Given
y = 9 - 4x
Substitute the given values of x into the equation and evaluate for y
x = - 2, then
y = 9 - 4(- 2) = 9 + 8 = 17 ⇒ (- 2, 17 ) ← ordered pair
x = 5, then
y = 9 - 4(5) = 9 - 20 = - 11 ⇒ (5, - 11 ) ← ordered pair
Find the zeros of the function

√-1 is imaginary number iStep-by-step explanation:
Step 1: Define function
k(x) = -5x² - 125
Step 2: Find roots
Set function equal to 0: 0 = -5x² - 125Factor out -5: 0 = -5(x² + 25)Divide both sides by -5: 0 = x² + 25Subtract 25 on both sides: -25 = x²Rewrite: x² = -25Square root both sides: x = ±√-25Rewrite: x = √-1 · ±√25Evaluate: x = ±5iThe coordinates of point A on a grid are (−3, −2). Point A is reflected across the y-axis to obtain point B. The coordinates of point B are ( , −2)
Answer:
Point B = ( 3 , -2)
Step-by-step explanation:
Flip across y axis means change x from negative to positive (or positive to negative)

rewrite the function f(x)=4(x-1)^2-2 in the form f(x)=ax^2+bx+c
Answer:
f(x) = 4x² - 8x + 2
General Formulas and Concepts:
Order of Operations: BPEMDASExpand by FOIL (First Outside Inside Last)Standard Form: f(x) = ax² + bx + cVertex Form: f(x) = a(bx + c)² + dStep-by-step explanation:
Step 1: Define function
Vertex Form: f(x) = 4(x - 1)² - 2
Step 2: Find Standard Form
Expand by FOILing: f(x) = 4(x² - 2x + 1) - 2Distribute 4: f(x) = 4x² - 8x + 4 - 2Combine like terms (constants): f(x) = 4x² - 8x + 29. A student received a 75% on an exam. If there were 20 questions on the exam,

What are rules for transformations and how do they work
Answer:
f (x) + b shifts the function b units upward.
f (x) – b shifts the function b units downward.
f (x + b) shifts the function b units to the left.
f (x – b) shifts the function b units to the right.
–f (x) reflects the function in the x-axis (that is, upside-down).
