Question

If f(x) = {-2x, x < 0, <4x, x > 0what is f(x) when x= -3?f(x)= 6f(x)= -5f(x)=-12f(x)= 1

Answer 1

Given the function:

`f(x)=\begin{cases}-2x,x<0 \\ 4x,x\ge0\end{cases}`

Let's find f(x) when x = -3

From the piecewise function, when x is -3(less than 0), f(x) is = -2x

Thus, to find f(x) when x = -3, we have:

f(x) = -2x

Substitute -3 for x:

f(-3) = -2(-3) = 6

f(-3) = 6

ANSWER:

f(x) = 6
