Question

What are the solution(s) to the following system of equations?
y = –x2
y = –x

Answer 1

y = –x2
y = –x

Answer 2

-x^2 = -x
x - x^2 = 0
x(1-x) = 0
x = 0 or 1

Answer 3

so which one would it be
a.(1, –1) and (–1, –1)
b. (0, 0)
c.(0, 0) and (1, –1)
d.(0, 0) and (–1, 1)

Answer 4

oh right - sorry - i didnt calculate the value of y
when x = 0, y = 0
when x = 1 , y = -1
so the answer is (0,0) and (1,-1)

c

Answer 5

i got these from plugging in values of x into y = -x

Answer 6

happy with that?
