Answer:To find this, all you have to do is plug in 3 where x is in the equation, which gives you this:
f
(
3
)
=
5
(
3
)
−
2
. From there, just find the value:
5
(
3
)
−
2
=
13
.
Step-by-step explanation: 13 is the answers sorry i looks like that
What is the question here that I should answer?
Step-by-step explanation:
x² - 2x - 15 = 0
x1 = 5
x2 = -3
Answer: 10 minutes. explanation; 5 x2 = 10
Vertex is directly in middle of directix and focus
distance from 8 to -8 is 16
16/2=8
so 8 below focus (since 8>-8) is the point (0,0
vertex is (0,0)
nice
it opens up because focus is above directix
also it goes up down so
4p(y-k)=(x-h)^2
(h,k) is veretx
we got that (h,k) is (0,0)
and p is distance from vertex to focus which is 8
so
4(8)(y-0)=(x-0)^2
32y=x^2
y=(1/32)x^2
