Question

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?

Answer 1

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.

Answer 2

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.
