Answer: -2
Explanation: the two negatives would cancel out each other and you will up with 8. then 8-10 is -2

don't get slipped up by f(x)! it just means y basically, and the number filled in for X, in this case -4, will go in the x spot! then just solve for H aka Y!

Which is the graph of the function f(x)= negative square root x
Vsevolod [243]
First, note that \sqrt{x} is always positive (except for x=0), so -\sqrt{x} must be always negative.

Thus, the only plausible graphs are 1 and 3 since they are below the x-axis.

Now, \sqrt{x} and -\sqrt{x} are only defined for x≥0, because only for these x'es we can take the square root. 

Note that the third graph has domain (-infinity, 0], so it is not the right one, while 1 is ok.


Answer: first graph

Two boats depart from a port located at (–10, 0) in a coordinate system measured in kilometers, and they travel in a positive x-
stiks02 [169]
To get the points at which the two boats meet we need to find the equations that model their movement:
Boat A:
vertex form of the equation is given by:
f(x)=a(x-h)^2+k
where:
(h,k) is the vertex, thus plugging our values we shall have:
f(x)=a(x-0)^2+5
f(x)=ax^2+5
when x=-10, y=0 thus
0=100a+5
a=-1/20
thus the equation is:
f(x)=-1/20x^2+5

Boat B
slope=(4-0)/(10+10)=4/20=1/5

thus the equation is:
1/5(x-10)=y-4
y=1/5x+2

thus the points where they met will be at:
1/5x+2=-1/20x^2+5
solving for x we get:
x=-10 or x=6
when x=-10, y=0
when x=6, y=3.2
Answer is (6,3.2)
