Graphing Quadratic Functions
Graph this function: f(x) = x2 - 4x - 5
Step 1: Identify a and b.
a = b = -40
Step 2: Find the vertex using the formula 1 =
I=
Check

Step-by-step explanation:

hello :

a= 1      b= -4  

the vertex is : ( -b/2a  ; f(-b/2a)

-b/2a = - (-4)/2 = 2

f(2) = (2)²-4(2)-5 = 4-13= -9

the vertex is : (2  ; -9)

it is definatly the 3rd one. very much looks like it, for a good chance, the third one would be best for you.

8(4)^8=72^feet to say that the total can conclude to 8(4) which as you know would mean 8 x 4. that equals 32w. 32^ could make a 72 answer as well. but your coefficent will remain w so your answer is 72w.

you!
