Just take the function, and wherever it says 'x', substitute '-3' .
Then it'll say f(-3) = -2(-3)² - 7(-3) + 6 . Surely you can solve that.
As my old Electronic Circuits professor used to tell us, back around 1962:
"If
f(x) = -2x² - 7x + 6
then
f(cow) = -2cow² - 7cow + 6 ."
Of all the things I learned from him, this is the thing I remember most.
Answer: 72.3
Step-by-step explanation: least to greatest would be 68.92, 69.15, 72.3, 73.2
So with that information and knowing that the lowest number represents the person who came in first, then we know 72.3 is the person who came in third place.
