The value of f(2) is -2 ⇒ 1st answer
Step-by-step explanation:
The form of the quadratic function is;
f(x) = ax² + bx + c, where
- a is the coefficient of x²
- b is the coefficient of x
- c is the numerical term
- x is the domain of the function and f(x) is the range of the function
∵ f(x) = -5x² - x + 20
- f(2) means value f(x) at x = 2
∵ x = 2
- Substitute x in the function by 2 to find f(2)
∵ f(2) = -5(2)² - (2) + 20
∴ f(2) = -5(4) - 2 + 20
∴ f(2) = -20 - 2 + 20
∴ f(2) = -2
The value of f(2) is -2

Answer:
<h2>7a-12</h2>
Step-by-step explanation:
Answer:
(1/2)x - y = -2
General Formulas and Concepts:
<u>Pre-Alg</u>
<u>Alg I</u>
Slope-Intercept Form: y = mx + b
- m - slope
- b - y-intercept
Standard Form: Ax + By = C
Step-by-step explanation:
<u>Step 1: Define equation</u>
Slope-Intercept Form: 2 + (1/2)x = y
<u>Step 2: Find Standard Form</u>
- Rewrite: y = (1/2)x + 2
- Subtract 1/2x on both sides: y - 1/2x = 2
- Factor negative: -(1/2x - y) = 2
- Divide both sides by -1: 1/2x - y = -2
