Will Mark Brainlest help pleaseeeeee

Masja [62]

Answer:

h(2) = 7/4

h(-3) = -2

h(-2) = 11/(-8)

h(-3) - h(-2) = -(5/8)

Step-by-step explanation:

h(x) = (2x^2-x+1) / (3x-2)

h(2) = (2*2^2 - 2 + 1) / (3*2 - 2)

= (8 - 2 + 1) / (6 - 2)

= 7/4

h(-3) = {2*(-3)^2 - (-3) + 1} / {3*(-3) - 2}

= (18 + 3 + 1) / (-9 - 2)

= 22/(-11)

= -2

h(-2) = {2*(-2)^2 - (-2) + 1} / {3*(-2) - 2}

= (8 + 2 + 1) / (-6 - 2)

= 11/(-8)

h(-3) - h(-2) = (-2) - {11/(-8)}

= -(5/8)

Hope this will help. Please give me brainliest.
