Answer:
a.(-2,-1)
b.(-3,0) and (-1,0)
Step-by-step explanation:
the roots are 2
Answer:
(f - g)(x) = -8x²
(f - g)(2) = -32
General Formulas and Concepts:
<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = -10x² - x
g(x0 = -2x² - x
(f - g)(x) is f(x) - g(x)
(f - g)(2) is f(2) - g(2)
<u>Step 2: Find (f - g)(x)</u>
- Substitute: (f - g)(x) = -10x² - x - (-2x² - x)
- Distribute -1: (f - g)(x) = -10x² - x + 2x² + x
- Combine like terms: (f - g)(x) = -8x²
<u>Step 3: Evaluate</u>
- Substitute: (f - g)(2) = -8(-2)²
- Evaluate: (f - g)(2) = -8(4)
- Multiply: (f - g)(2) = -32
And we have our answers!
X = (12/5,0)
y = (0,-4)
substitute 0 in for y & solve for x , to find the y-intercept substitute 0 in for x and then solve . ( I hope that makes sense)
10x +4 </ 25 (the </ is a less than or equal to sign)
