Answer 1

@Ciarán95

Answer 2

what is the question?

Answer 3

how many real roots does the function have.....i think its three

Answer 4

yes Do you know what they are?

Answer 5

intersections at the line maybe

Answer 6

yes at the intersection of the line with the x-axis (when f)x) = 0)

Answer 7

so how would i complete the graphed function than

Answer 8

we have an intersection at x = 1 so thats one root
The other 2 are 'double' roots - where the graph just touches x = -2

so the 3 roots are 1, -2 (multiplicity 2)

Answer 9

y=(x- ) (x+ )^2 so what would i put in the blanks of this equation intresections of the x axis?

Answer 10

2 an then 1 ?

Answer 11

(x - __) = 0 and (x +__) = 0

just replace the __ by 1 and -2

Answer 12

* (x + __)^2 = 0 i should have written

Answer 13

it wont let me put -2 as an awnser .......thats why i put it in the first equation

Answer 14

first part of the equation*

Answer 15

oh sorry my mistake its 2 goes there not -2

Answer 16

because if (x + 2)&2 = 0 then x = -2

Answer 17

okay thankyou

Answer 18

yw

Answer 19

oh i see

Answer 20

and (x - 1) = 0 gives x = 1
