The volume of a cube is found by cubing the edge length — or multiplying it by itself twice.
In other words, the volume of a cube is as follows:
Simplified:
To find the edge length from the volume, you'd have to do the opposite, which is to find the cubic root.
What do you need help with?
This can be determined by finding the x-intercept. In doing so, we let y=0 to find the value of x.
y= 2x^2 -x -3
[0 = 2x^2 -x-3]÷2
0 = x^2 -1/2 x - 3/2
Complete the squares:
1/16 + 3/2 = x^2 - 1/2x + 1/16
25/16 = (x -1/4)^2
sqrt (25/16) = x - 1/4
+/- 5/4 = x - 1/4
Thus,
x = 1/4 + 5/4 = 3/2
x = 1/4 - 5/4 = -1
Thus, the graph crosses at x = 3/2 and x = -1.
C I am soooo sorry if I’m wrong
