PLZ HELP! Use the parabola tool to graph the quadratic function f(x)=-x^2+4
Graph the parabola by first plotting its vertex and then plotting a second point on the parbola.​

vertex and x= -b/2a = 0

second point, when x=1, y=3

third point the mirror of the second point over the vertex

Step-by-step explanation:

Do as described

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

1. sometimes

2. never true

3. sometimes

step-by-step explanation:

these are pretty self explanatory if you know what supp right and com angles are
