What is the axis symmetry of f(x) = x2 – 9x + 8

x=4.5

Step-by-step explanation:

The question is in standard form as y = ax^2 + bx + c.

And as such, the axis of symmetry is given as x = - b / 2a

From the question above, a =1 and b = - 9

Therefore axis of symmetry is;

x = - (-9) / 2(1) which gives;

x = 9/2 or x=4.5
