liana started to evaluate the function f(x) = 2x² - 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? 9 10 16 17
Answer
Explanation:
Step1: Calculate the square term
$f(2)=2\times4 - 3\times2+7$ (since $2^2 = 4$)
Step2: Calculate the multiplications
$f(2)=8 - 6+7$ (because $2\times4 = 8$ and $3\times2 = 6$)
Step3: Calculate the sub - traction and addition
$f(2)=2 + 7=9$
Answer:
A. 9
