Liana started to evaluate the function f(x) = 2x^2 – 3x + 7 for the input value 2. f(x) = 2(2)2 – 3(2) + 7 = 2(4) – 3(2) + 7 what is the value of the function when x = 2?
a. 9
b. 10
c. 16
d. 17

For this case we have the following function:
 
  we can use the steps that liana wrote to evaluate the function:
  evaluating for x = 2 we have:
 
  completing liana's work we have:
 
  answer:
  the value of the function when x = 2 is:
  a. 9

So lets see what would the value of the quadratic function be if we input x=2 into the function f(x)=2x^2 - 3x + 7. so we simply check the value when we put x=9 to the quadratic function: f(2)= 2*2^2 - 3*2 +7= 2*4 - 6 +7 = 8-6+7= 9. so the correct answer is a. 9.
