Y x 2 40

Y x 2 40-A turning point is a point where the graph of a function has the locally highest value (called a maximum turning point) or the locally lowest value (called a minimum turning point) A function does not haveDivide y, the coefficient of the x term, by 2 to get \frac {y} {2} Then add the square of \frac {y} {2} to both sides of the equation This step makes the left hand side of the equation a perfect square x^ {2}yx\frac {y^ {2}} {4}=4y^ {2}\frac {y^ {2}} {4} Square \frac {y} {2}

Then the base b logarithm of x is equal to y log b (x) = y For example when 2 4 = 16 Then log 2 (16) = 4 Logarithm as inverse function of exponential function The logarithmic function, y = log b (x) is the inverse function of the exponential function, x = b yMethod finding stationary points Given sked) calculate the y coordinate (s) of the The original question from Anuja asked how to draw y 2 = x − 4 In this case, we don't have a simple y with an x 2 term like all of the above examples Now we have a situation where the parabola is rotated Let's go through the steps, starting with a basic rotated parabola Example 6 y 2 = x The curve y 2 = x represents a parabola rotated

Input, x Output, y 1 3 2 4 3 5 4 6 y = x 2 3 = 1 2 4 = 2 2 5 = 3 2 6 = 4 2 EXAMPLE 1 Completing InputOutput Tables Write an equation for the function Then copy and complete the table a The output is 1 less b The output is twice than the input the input Input, x 234 5 Output, y Input, x 036 9 Output, y a An equation is y = xIn implicit differentiation, we differentiate each side of an equation with two variables (usually and ) by treating one of the variables as a function of the other This calls for using the chain rule Let's differentiate for example Here, we treat as an implicit function of Add 4 to both sides 4 = (x 3)2 Square root both sides ±2 = x 3 Subtract 3 from both sides x = − 3 ± 2 xintercepts → (x,y) = ( − 5,0) and ( − 1,0) You may if you so choose determine the vertex from this point xvertex is midway between the x intercepts then by substitution determine y
