Answer:
all x intercepts [-4, 0] [4, 0]
Step-by-step explanation:
x-intercept, i.e. y=0
f(x) = x^3 - 4x^2 - 16x + 64 = 0
(x^3 + 4^3) - 4x^2 - 16x = 0 [FYI, x^3 + y^3 = (x + y)(x^2 - xy + y^2)]
(x + 4)(x^2 - 4x + 16) - 4x^2 - 16x = 0
(x + 4)(x^2 - 4x + 16) - 4x(x + 4) = 0
(x + 4)(x^2 - 4x + 16 - 4x) = 0
(x + 4)(x^2 - 8x + 16) = 0
(x + 4)(x - 4)^2 = 0
x = -4 or 4
all x intercepts [-4, 0] [4, 0]
Answer:
<em>The point (-3,2) is not a solution of the inequality</em>
Step-by-step explanation:
<u>Inequality</u>
Inequalities relate the left and the right side of an expression with an operator other than the equal sign.
The inequality given in the question is

There are many combinations of r and y that make inequality be true. For example, for r=1 and y=1


This relation is true since -14 is less than -9.
Also, there are many combinations that make the given inequality be false.
For example, for r=2 and y=-1



This inequality is false.
Let's test the point (-3,2)



Which is false, thus the point (-3,2) is not a solution of the inequality
