Answer:
7(x+1)^2 - 3
Step-by-step explanation:
To Write in The Vertex Form Simply means expressing the equation using completing of the square method
step 1: Make the coefficient of x^2 to 1
7 [x^2 + 2x + 4/7]
step 2: express the coefficient of x as half's of positive and negative
7 [x^2 + 2x + (1)^1 - (1)^1 + 4/7]
step 3: separate the negative part and the constant to solve then correct x^2 and 1^2 together
7 [ (x+1)^2 -3/7 ]
step 4 : distribute the 7
7(x + 1)^2 - 3
Answer: i dont know if im right nbut the answer is 4
Step-by-step explanation:
Answer:
A= -4
B= 4
C= 1/4
D= -1/4
Step-by-step explanation:
I see u counted which is good. remember it's rise over run so for a u got up down 4 over 1. that's why the slope would be -4. You figure out the other ones the same way.
Answer:
c
Step-by-step explanation:
and the answer is c
F(x) = x^4 + 7x^3 - 7x^2 - 43x + 42
f(1) = 1^4 + 7(1)^3 - 7(1)^2 - 43(1) + 42 = 1 + 7 - 7 - 43 + 42 = 0
Since f(1) = 0, therefore (x - 1) is factor.
