Answer:
c = -11
expression value = 245
c = 0
expression value = 3
c = 15
expression value = 453
Step-by-step explanation:
Given expression = [tex]2c^2 + 3[/tex]
for c = -11 , we put c in place of c in given expression
[tex]2(-11)^2 + 3 = 2(121) + 3 = 242 + 3 = 245[/tex]
for c= 0
[tex]2(0)^2 + 3 = 2(0) + 3 = 0 + 3 = 3[/tex]
for c = 15
[tex]2(15)^2 + 3 = 2(225) + 3 = 450 + 3 = 453[/tex]
