Step-by-step explanation:
Given :polynomial 3y - 4y + 11
if y=2
Find : the value if y = 2
Solving : Let p(y) = 3y - 4y + 11
substitute y value in the given polynomial
p(y) = 3y - 4y + 11
=> p(2) = 3(2) - 4(2) + 11
=> p(2) = 6 - 8 + 11
=> p(2) = 17-8
=> p(2) = 9
therefore the value of the polynomial 3y - 4y + 11 at y=2 is 9
