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 powers
$f(2)=2\times(2)^2 - 3\times(2)+7=2\times4 - 3\times(2)+7$
Step2: Perform multiplications
$2\times4 - 3\times(2)+7 = 8-6 + 7$
Step3: Do subtractions and additions
$8-6 + 7=2 + 7=9$
Answer:
9
