Create Function Table: question_prompt: Create a function table for the line $y=-2x+3$ and find the value of $f(3)$ for the function $f(x)=3x$ .
Calculate y values: For the function table of $y=-2x+3$ , choose values for $x$ and calculate corresponding $y$ values. Let's pick $x$ values of $-1$ , $0$ , $1$ , $2$ .
Calculate $f(3)$ : Calculate $y$ when $x=-1$ : $y=-2(-1)+3 = 2+3 = 5$ .
Calculate $f(3)$ : Calculate $y$ when $x=-1$ : $y=-2(-1)+3 = 2+3 = 5$ . Calculate $y$ when $x=0$ : $y=-2(0)+3 = 0+3 = 3$ .
Calculate $f(3)$ : Calculate $y$ when $x=-1$ : $y=-2(-1)+3 = 2+3 = 5$ . Calculate $y$ when $x=0$ : $y=-2(0)+3 = 0+3 = 3$ . Calculate $y$ when $x=1$ : $y=-2(1)+3 = -2+3 = 1$ .
Calculate $f(3)$ : Calculate $y$ when $x=-1$ : $y=-2(-1)+3 = 2+3 = 5$ . Calculate $y$ when $x=0$ : $y=-2(0)+3 = 0+3 = 3$ . Calculate $y$ when $x=1$ : $y=-2(1)+3 = -2+3 = 1$ . Calculate $y$ when $y$ $1$ : $y$ $2$ .
Calculate $f(3)$ : Calculate $y$ when $x=-1$ : $y=-2(-1)+3 = 2+3 = 5$ . Calculate $y$ when $x=0$ : $y=-2(0)+3 = 0+3 = 3$ . Calculate $y$ when $x=1$ : $y=-2(1)+3 = -2+3 = 1$ . Calculate $y$ when $y$ $1$ : $y$ $2$ . Now, let's find $f(3)$ for $y$ $4$ . Calculate $f(3)$ : $y$ $6$ .
