Well, evaluating a function means plugging whatever they gave me in for the argument in the formula. This means that I have to plug this character "§" in for every instance of x. Here goes:

f (§) = (§)2 + 2(§) – 1

= §2 + 2§ – 1

This is definitely weird-looking, but it follows all the rules they gave me, so:

f (§) = §2 + 2§ – 1

Answer:

f(-3) = 15

Step-by-step explanation:

f(x)= 2x^2 - 3

Plug in x = -3 into the function

f(-3) = 2(-3)^2 - 3

f(-3) = 18 - 3

f(-3) = 15
