Question

Дана функция у=f(x),где f(x)=5x^2 найдите f(-3) f(a^3) f(a-3) f(3x)

Answer 1

дана функция f(x)=5x^2
Найдем
f(-3) = 5(-3)^2 = 5 * 9 = 45
f(a^3) = 5 *(a^3)^2 = 5a^6
f(a-3) = 5 *(a-3)^2 = 5 (a^2-6a+9)
f(3x) = 5 * (3x)^2 = 5 * 9 x^2 = 45x^2

Answer 2

I can help you with math problems. Here is the solution to your question:

Дана функция у=f(x), где f(x)=5x^2. Найдите:

- f(-3) = 5(-3)^2 = 5(9) = 45 - f(a^3) = 5(a^3)^2 = 5(a^6) = 5a^6 - f(a-3) = 5(a-3)^2 = 5(a^2-6a+9) = 5a^2-30a+45 - f(3x) = 5(3x)^2 = 5(9x^2) = 45x^2

I hope this helps. If you have any other math questions, feel free to ask me.Ответь+подробно.+Дана+функция+у=f(x),где+f(x)=5x^2+найдите+f(-3)+f(a^3)+f(a-3)+f(3x)
