Given f(x)=-x+3, solve for x when f(x)=0. Answer:

Set Function Equal to 0: Set the function f(x) equal to 0. We are given f(x) = -x + 3 and we need to find x when f(x) = 0. So, we set the equation -x + 3 = 0.Solve for x: Solve for x. To find x, we need to isolate it on one side of the equation. -x + 3 = 0 Add x to both sides to get x on the right side and numbers on the left side. -x + x + 3 = 0 + x 3 = x

Answer:

Set Function Equal to $0$ : Set the function $f(x)$ equal to $0$ . We are given $f(x) = -x + 3$ and we need to find $x$ when $f(x) = 0$ . So, we set the equation $-x + 3 = 0$ .
Solve for x: Solve for x. $\newline$ To find x, we need to isolate it on one side of the equation. $\newline$ $-x + 3 = 0$ $\newline$ Add x to both sides to get x on the right side and numbers on the left side. $\newline$ $-x + x + 3 = 0 + x$ $\newline$ $3 = x$
