Question

Найдите значение функции f(x)=x(2x+3) при x=-1

Answer 1

f(x)=x(2x+3)

при x=-1

f(-1) = (-1)(2*(-1) + 3) = -(-2+3) = -1

Answer 2

f (x)=2x^2+3x; x=-1

f (x)=2*(-1)^2+3*(-1)

f (x)=2*1-3

f (x)=-1

Answer 3

To find the value of the function f(x) = x(2x + 3) when x = -1, you simply substitute -1 for x in the expression:

f(-1) = (-1)(2(-1) + 3)

Now, perform the calculations step by step:

f(-1) = (-1)(-2 + 3) f(-1) = (-1)(1) f(-1) = -1

So, the value of the function f(x) = x(2x + 3) when x = -1 is -1.
