Question

Draw the graph of polynomial f(X)=4x^2+4x-1

Answer 1

Step-by-step explanation:

1) By using the quadratic formula we derive the discriminant

D = b^2-4ac

D= 4^2 - 4*4*1

D= 16-16

D= 0

Now,

x = -b+√D/2a and -b-√D/2a

x = -4+0/2 and -4-0/2

x = -2 and -2

To plot the graph, draw a line parallel to the y-axis and passing through -2 on the x-axis.
