Question

find the vertex of y= 4x^2+5x+-6 please find the value of x and value of y and round to the nearest hundredth

Answer 1

Answer:

x=-0.63,y=-7.56

Step-by-step explanation:

if you know the general formula of the quadratic function

$x = -\frac{ - b + - \sqrt{b^{2} - 4ac } }{2a}$

then you need to that the line of symmetry is equal to average of the sum of roots

which means

$\frac{ - b}{2a}$

as the sum is equal to -b/a

you also need to the know the quadratic equation symbols

$ax ^{2} + bx + c$

all you need now is to plug the values in this formula to get x coordinate then you subsitute x to get the y
