lol

can u help?

[manic mortar]

-f(x) means reflection over the x-axis meaning the x-intercepts of y = f(x) is equal to that of y = -f(x)

[exotic nimbus]

i put my answers at 0,11 and 6,0 and 3,0 but it was wrong

for some reason

[manic mortar]

yes it's wrong

[exotic nimbus]

why?

[manic mortar]

x-intercepts: (-6, 0), (-3, 0)
y-intercept: (0, -11)

[manic mortar]

try to reflect f(x) over the x-axis

[exotic nimbus]

oh i see

and 0 doesnt change

because -0 = 0

okay i understand thanks man

[manic mortar]

urwelcome

[exotic nimbus]

@manic mortar

can u help again?

easier question but im still stuck

i know c

but m is confusing me

[manic mortar]

there is a point (1, -2) other than the y-intercept

[exotic nimbus]

is it 5?

nope its not

[manic mortar]

-5

[exotic nimbus]

how

[manic mortar]

use the y-intercept and this point

m = (y2 - y1)/(x2 - x1)

m = (3 - (-2))/(0 - 1)

[exotic nimbus]

0?

whered u get that lol

[manic mortar]

y-intercept means the point where the graph intersects the y-axis

meaning x = 0

and vice versa

[exotic nimbus]

so m = 1/-1?

[manic mortar]

no

[exotic nimbus]

5/-1

[manic mortar]

3 - (-2) = 3 + 2

[manic mortar]

yes

[exotic nimbus]

so m = 5?

[manic mortar]

-5

cuz divided by -1

positive divided by negative equals negative
