The inequalities are 2x 3y ≥ 6, x y ≥ 3 and y ≤ 2 Rewrite the inequalities so that solves for y , That's the slope intercept form and it will make the boundary line easier to graph 1) Draw the coordinate plane The first inequality 2x 3y ≥ 6 3y ≥ 2x 6 y ≥ ( 2/3)x 2 2) Graph the line y = ( 2/3)x 2 3) Since the inequality symbol is ≥ the boundary is \(2 x3 y=6, \quad 3 x=4 y7, \quad y=2 x5, \quad 2 y=3, \quad \text { and } \quad x2=0\) A line is completely determined by two points Therefore, to graph a linear equation, we need to find the coordinates of two points This can be accomplished by choosing an arbitrary value for x or y and then solving for the other variableAfter you enter the expression, Algebra Calculator will graph the equation y=2x1 Here are more examples of how to graph equations in Algebra Calculator Feel free to try them now Graph y=x^22x y=x^22x Graph y= (x3)^2 y= (x3)^2
Y = x 2 2x 3 is a parabola Since the x 2 is positive, it opens upward (concaveup) If you factor the right hand side, you get (x1) (x3) so that means that the xintercepts are at 1 and 3 The vertex is halfway between these of course (at x = 1) That means the vertex is at x = 1 and y = 1 2Y = x²4x3 (0,3); In this function, x = 1 would make y = 8/0 which is undefined To find this, just set the denominator equal to zero and solve for x 2x 2 = 0 2x = 2 x = 1 The function is defined for all other numbers, so the domain is (infinity, 1)U(1, infinity) I can't remember off hand any good way to find the range other than graphing the function
Changing "c" only changes the vertical position of the graph, not it's shape The parabola y = x 2 2 is raised two units above the graph y = x 2 Similarly, the graph of y = x 2 3 is 3 units below the graph of y = x 2 The constant term "c" has the same effect for any value of a and b Parabolas in the vertexform or the ahk form, y = a(x y=(x1)^216 >"the equation of a parabola in "color(blue)"vertex form" is •color(white)(x)y=a(xh)^2k "where "(h,k)" are the coordinates of the vertex and a" "is a multiplier" "to obtain this form "color(blue)"complete the square" y=x^22(1)x color(red)(1)color(red)(1)15 y=(x1)^216larrcolor(red)"in vertex form" To graph this, we'll need y y intercepts We find these just like we found x x intercepts in the previous couple of problems y 2 − 6 y 5 = 0 ( y − 5) ( y − 1) = 0 y 2 − 6 y 5 = 0 ( y − 5) ( y − 1) = 0 The parabola will have y y intercepts at y = 1 y = 1 and y = 5 y = 5 Here's a sketch of the graph
