Answer:
Step-by-step explanation:
perhaps you mean
x^3+y^3+z^3 = 3xyz
because
x+y+z = 0
x^3 + y^3 + z^3 - 3xyz = (x + y + z )(x^2 + y^2 + z^2 -xy - yz - xz)
(this equation is an identity)
x^3 + y^3 + z^3 - 3xyz = (<em>x + y + z</em> )(x^2 + y^2 + z^2 -xy - yz - xz)
x^3 + y^3 + z^3 - 3xyz = (<em>0</em>)(x^2 + y^2 + z^2 -xy - yz - xz)
x^3 + y^3 + z^3 - 3xyz = 0
x^3 + y^3 + z^3 = 3xyz

Answers: b, d and e
b.The graph has a relative minimum
d. The graph has an x intercept at 3,0
e. the graph has an y intercept at 0,-15
f(x)=(x+5)(x-3)
The given equation is in the form of f(x) = a(x-b)(x-c)
If 'a' is positive then graph has a relative minimum
If 'a' is negative then graph has a relative maximum
Here a=1 that is positive so graph has a relative minimum .
To find x intercept we set f(x) =0 and solve for x
0=(x+5)(x-3)
x+5 =0 -> x = -5 so x intercept is (-5,0)
x - 3=0 -> x= 3 so x intercept is (3,0)
To find y intercept we plug in 0 for x
y=(x+5)(x-3)
y=(0+5)(0-3) = -15
so y intercept is (0,-15)
Answer:
4
Step-by-step explanation:
Basically the y - intercept is where the graph intercepts with the y axis. The y axis is the vertical line in the middle of the graph. As you can see, the the graph and the y axis intersect at about 4.
Answer:
I think the correct answer is 18
