Find the axis symmetry of x y=4x-6x+3

x = 0.75.

Step-by-step explanation:

y = 4x^2 - 6x + 3.

( I have assumed that the first term is 4x^2 not 4x).

Convert to vertex form:

y = 4(x^2 - 1.5x) + 3

y = 4[ (x - 0.75)^2 - 0.5625 ] + 3

y = 4(x - 0.75)^2 - 2.25 + 3

y = 4(x - 0.75)^2 + 0.75.

So the axis of symmetry is x = 0.75.

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
