Question

What is the equation for the axis of symmetry in the function? y = -2x2 + 5x - 4
y = 5/4
x = 5/4
y = -2/5
x = -2/5

Answer 1

anything of the form

y = ax^2 + bx + c

has the axis of symmetry of

x = -b/(2a)

Answer 2

x=-5/-4

Answer 3

reduce that

Answer 4

what do you get when you do so?

Answer 5

x=5/4

Answer 6

good
