if you want to know how , comment, or you are good to go !
Rounded to the tenth: 3.3
Square roots that are not perfect squares are always
irrational
A.A’(5,-5),B’(1,-5),C’(1,-2)
Answer:
Graph the parabola using the direction, vertex, focus, and axis of symmetry.
Direction: Opens Down
Vertex:
(
2
,
4
)
Focus:
(
2
,
15
/4
)
Axis of Symmetry:
x
=
2
Directrix:
y
=
17
/4
x y
0 0
1 3
2 4
3 3
4 0
To find the x-intercept, substitute in
0 for y and solve for x
. To find the y-intercept, substitute in 0 for x and solve for y
.
x-intercept(s): (
0
,
0
)
,
(
−
4
,
0
)
y-intercept(s): (
0
,
0
)
Step-by-step explanation:
f' = -4x+8=0 => x=2
=> f(2) is the maximum = 11
