Question

Функция задана формулой f(x)=x^+5x.Найдите f(-1)

Answer 1

F(x)=x²+5x
f(-1)=(-1)²+5*(-1)=1-5=-4

Answer 2

To find the value of the function f(x) at x = -1, you simply need to substitute -1 into the formula for f(x) and perform the calculation.

Given the function f(x) = x^2 + 5x, plug in x = -1:

f(-1) = (-1)^2 + 5(-1)

Now calculate:

f(-1) = 1 - 5

f(-1) = -4

So, f(-1) = -4.
