Answer:
(f-g)(x) = - 3 x² + 3 x -6
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given function f(x) = x² + x - 5
g(x) = 4 x² - 2 x + 1
(f-g)(x) = f(x) - g(x)
= x² + x - 5 - (4 x² - 2 x + 1)
= x² - 4 x² + x + 2 x - 5 -1
= - 3 x² + 3 x -6
(f-g)(x) = - 3 x² + 3 x -6
From the number given is appears the rule is y = 2x + 1
This works for all three:
17 = 2(8) + 1
1 = 2(0) + 1
15 = 2(7)+1
Answer:
Graph A is the answer
Step-by-step explanation:
Answer:
Step-by-step explanation:
x²-3x-2=0
delta = b² - 4ac a=1 b = -3 c = -2
delta = (-3)² - 4(1)(-2) =17
X1 = (3-√17)/2 ≃ - 0.56
x2 =(3+√17)/2 ≃3.56
The correct answer is c I think
