Answer:
(√3-√6) / (√3+√6)
Step-by-step explanation:
Answer:
a) (-2,-2)
b) (0,1)
Step-by-step explanation:
(0,-5) is the vertex of the initial function.
(0-2,-5+3)
(-2,-2)
(0,-5)
Reflected in the x-axis : (0,5)
4 units down: (0,1)
What is the mean of the following data set?<br>
{4, 5, 2, 4, 9, 7, 5, 5, 2, 8, }

If I'm not mistaken you add the numbers up, then you divide it by the amount of numbers there. 4 + 5 + 2 + 4 + 9 + 7 + 5 + 5 + 2 + 8 = 51
51 / the amount of numbers there (10) = 5.1
Hope this helps :)
The function can be factorised to give x²(x²-5). Therefore the graph will touch the x axis at zero and cut it at -√5 and √5, giving three x-intercepts. To check, let's look at a graph my calculator drew of this function:
