Para cada una de las siguientes funciones cuadráticas, calcula las coordenadas del vértice. Recuerda reescribir la misma de la forma y = Ax2 + Bx + C para así determinar los coeficientes A, B, C.
a. f(x)=-x2 +3
b. y–2=3x2 –6x
c. (x–3)2+2y–11=0
d. y–5x+2x2 +9=0

answer: can you give the

step-by-step explanation:

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.

      2

  2 is to go somewhat to the top right of a because it is squared    

v= a h/3

x=25tan30=14.43 or the answer is b
