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

poizon [28]

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).

What is the measure of angle x enter your answer is the box

evablogger [386]

Answer:

83 degrees

Step-by-step explanation:

vertical degrees show that angles across from one another have the same value. All three angles will add up to 180 degrees. Subtract both 56 and 41 from 180 degrees to get a remainder of 83.
