Question

Given the function f(x) =2x^2 -5x+8 state the equation of the axis of symmerty of the function.

Answer 1

Answer:

X=5/4

Step-by-step explanation:

As we know that we get maxima when differentiation of f(x) is zero.

so

by differentiating f(x) w.r.t x

d f(x)/dx = 4x-5 =0

4x=5

x=5/4

Hence the axis of symmetry is x=5/4.
