Algebra.Com's Answer #355951 by KMST(5328)![]() ![]() You can put this solution on YOUR website! That is a linear function, and the graph will be a straight line. You only need two points to determine a straight line. \n" ); document.write( "You could calculate the value of the function for two different values of x, plot the points, and draw the line. \n" ); document.write( "For example, for x=-3, the value of the function is \n" ); document.write( "f(-3)=-(-3+3)+2=-0+2=2 \n" ); document.write( "and you would plot the point A(-3,2) on your graph. \n" ); document.write( "Then if you pick x=4, for x=4, the value of the function is \n" ); document.write( "f(4)= -(4+3)+2=-7+2=-5 \n" ); document.write( "and you would plot the point B(4,-5) on your graph. \n" ); document.write( "The y-intercept is the point where the line intersects the y-axis, which is the vertical line described by the equation x=0. So the point with x=0 and y=f(0) is the y-intercept, but usually you just give they value, because everybody knows that x=0 is the x value. \n" ); document.write( "In your case, f(0)=-(0+3)+2=-3+2=-1. \n" ); document.write( " |
