\( f(2) = 5 \)

Solución

Verilen fonksiyon \( f(x) = x^2 + 2x - 3 \) ve \( f(2) \) değerini bulmamız gerekiyor. Öncelikle \( x = 2 \) değerini fonksiyona yerleştirelim: \[ f(2) = 2^2 + 2 \cdot 2 - 3 \] Hesaplayalım: \[ f(2) = 4 + 4 - 3 \] \[ f(2) = 8 - 3 \] \[ f(2) = 5 \] Sonuç olarak, \( f(2) = 5 \).

Bonus Knowledge

To find \( f(2) \), just plug \( x = 2 \) into the function \( f(x) = x^2 + 2x - 3 \). So, \[ f(2) = 2^2 + 2(2) - 3 \\ = 4 + 4 - 3 \\ = 5 \] Therefore, \( f(2) = 5 \). Now you have the value of the function at \( x = 2 \)!

An investor plans to put a total of \( \$ 110,000 \) in a money market account, a bond fund, an international stock fund, and a domestic stock fund. She wants \( 60 \% \) of her investment to be conservative (money market and bonds). The investor wants the amount in international stocks to be one-fourth the amount in domestic stocks. Finally, the investor needs an annual return of \( \$ 4,400 \). Assuming the investor gets annual returns of \( 2.5 \% \) on the money market account, \( 3.5 \% \) on the bond fund, \( 4 \% \) on the international stock fund, and \( 6 \% \) on the domestic stock fund, how much should the investor put in each investment? The investor should put \( \$ 8800 \) in the international stock fund. (Type a whole number.) The investor should put \( \$ \square \) in domestic stock fund. (Type a whole number.)
