Find the x and y intercepts of y = 2x^3 - 4x^2 algebraically

The x-intercept is the place where y = 0 and the y-intercept is the point where x = 0. Using this information, we can substitute 0 in for x and y to find the intercepts.


x-intercepts (where y = 0):

2x^3 - 4x^2 = 0

x^2(2x - 4) = 0

Here we can apply the Zero Product Property to find x^2 = 0 and 2x - 4 = 0 separately.

x^2 = 0

x = 0

AND

2x - 4 = 0

2x = 4

x = 2

The x-intercepts are located at (0, 0) and (2, 0).


y-intercept (where x = 0):

y = 2(0)^3 - 4(0)^2

y = 0

The y-intercept is located at (0, 0).

Which number line represents the solution set for the inequality-1/2x>_4
Vesna [10]

Answer:

B

Step-by-step explanation:

Firstly, we solve for x

-x ≥ 8

Multiply both sides by -1

x ≤ -8

So we look at the inequality represented by this;

We can see that the correct inequality is option B;
