Y= - x^2 + 4x + 6 in vertex form

serg [7]

<h3>HI THERE!</h3>

$\rm \color{lime}(2,10)$

step-by-step explanation:

$\rm \color{lime}y = - {x}^{2} + 4x + 6$

identify the coefficients

<h2 /><h2> $\rm \color{lime}a = - 1,b = 4$ </h2>

substitute the coefficient into the expression
find the x-coordinate of the vertex by substituting a = - 1 and b=4 
 $\tt \tiny \: x = - \frac{b}{29}$

 $\rm \color{lime}x = - \frac{4}{2x( - 1)}$ 

solve the equation for X
find the y-coordinate of the vertex by evaluating the function for x = 2

 $\rm \color{lime}y = - {x}^{2} + 4x + 6,x = 2$ 

calculate the function value for x = 2

$\rm \color{lime}y = 10$

since the value of the function is 10 for x = 2 the vertex of the graph of the quadratic function is a (2,10)

 $= \rm \color{hotpink} (2,10)$ 

hope it helps
