7a Graphing Quadratic Functions Practice

The axis of symmetry is the xcoordinate vertex of the parabola The general form to find the axis of symmetry is For y =x^2 4x 2, a=1, b=−4 and c=2 If the function is symmetrical about the line x=0, it is an even function, so cannot have any odddegree terms The only viable choice is1) y = x^2 4x 2 First find the axis of symmetry (x= b/(2a)) find the vertex from that and it helps you choose the values for x when you make your x/y tables In this equation a = 1;

Y=x^2-4x+1 axis of symmetry

Y=x^2-4x+1 axis of symmetry-Substitute a and b into the formula x = (4)/2(2) This simplifies to 4/4, which is then simplified to 1 Therefore the axis of symmetry is x = 1X = b/2a Substituting the values of a and b,

Graphing Quadratic Equations Elementary Algebra

Y = − ( x 2) 2 3 y = ( x 2) 2 3 Use the vertex form, y = a ( x − h) 2 k y = a ( x h) 2 k, to determine the values of a a, h h, and k k a = − 1 a = 1 h = − 2 h = 2 k = 3 k = 3 Since the value of a a is negative, the parabola opens down Opens Down Find the vertex ( h, k) ( h, k)Y=x^24x32 is in the form y=ax^2 bx c The symmetry of that form would be a vertical line with the equation Determine first the value of 'a' andX^ {2}4x=4y12 Divide y3 by \frac {1} {4} by multiplying y3 by the reciprocal of \frac {1} {4} x^ {2}4x2^ {2}=4y122^ {2} Divide 4, the coefficient of the x term, by 2 to get 2 Then add the square of 2 to both sides of the equation This step makes the left hand side of the equation a

Correct answers 2 question Find the axis of symmetry and vertex for the equation belowy=−x^2−4x1Axis of symmetry is x=Vertex is ( , )Example 1 Find the axis of symmetry of the quadratic equation y = x 2 4x 3 Solution Given y = x 2 4x 3 Using axis of symmetry formula, x = b/2a x = (4)/2(1) x = 4/2 = 2 Therefore, axis of symmetry of equation y = x 2 4x 3 is x = 2 Example 2 Find the axis of symmetry of a parabola y = 4x 2 Solution Using axis of symmetry formula, x = b/2a This means that it IS equivalent to the original equation since all we would need to do is multiply the whole thing by "1" to get back to the original equation Therefore, in this case we have symmetry about the origin c y4x3 −5x = 0 y 4 x 3 − 5 x = 0 Show Solution First, check for symmetry about the x x axis

the target is to put the equation under the form f(x) = a(x h)^2 k and we see that f(h C) = f(h C) < what matters is the gap to point h therefore we conclude that x = h is axis of symmetry so here y = –2x² 4x –6 gives y = –2(x² 2x 1) 4 (complete the square !) y = 2(x1)^2 4 hence x = 1 is axis of symmetryStart with y = 1/x Try swapping y with x x = 1/ y Now rearrange that multiply both sides by y xy = 1 Then divide both sides by x y = 1/x And we have the original equation They are the same So y = 1/x has Diagonal Symmetry
