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?

    If you would like to know the value of the function when x = 2, you can calculate this using the following steps:

    f (x) = 2 * x^2 - 3 * x + 7

    x = 2

    f (2) = 2 * 2^2 - 3 * 2 + 7 = 2 * 4 - 6 + 7 = 8 - 6 + 7 = 9

    The correct result would be 9.

    F (x) = 2x² - 3x + 7

    x = 2

    f (2) = 2 (2²) - 3 (2) + 7

    f (2) = 2 (4) - 6 + 7

    f (2) = 8 - 6 + 7

    f (2) = 15 - 6

    f (2) = 9

    The value of the function when x = 2 is 9.
