The function h(x) = –2x2 + 8x written in vertex form is h(x) = –2(x – 2)2 + 8. the function h(x) is shown on the graph along with the parent function, f(x) = x2.
which statement is true concerning the vertex and axis of symmetry of h(x)?

the vertex is at (0, 0) and the axis of symmetry is x = 2.
the vertex is at (0, 0) and the axis of symmetry is y= 2.
the vertex is at (2, 8) and the axis of symmetry is x = 2.
the vertex is at (2, 2) and the axis of symmetry is y = 2.

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
