PUES COMO TE DIGO

For functions, the two notations mean the exact same thing, but "f(x)" gives you more flexibility and more information. ... Now you say "f(x) = 2x + 3; find f(–1)" (pronounced as "f-of-x is 2x plus three; find f-of-negative-one"). ... 7. Given f(x) = x2 + 2x – 1, find f(–3). f(–3) = (–3)2 +2(–3) – 1 = 9 – 6 – 1 = 2 ... Then f(1) = (1) + 4 = 5.
