If y = 2x3 – 4x and , find when x = 1. Give only the numerical answer. For example, if = 3, type only 3.
hey, honor student -- find what when x=1?
assume you mean
y = 2 x^3 - 4 x
dy/dx = 6 x^2 - 4
if x = 1
dy/dx = 6-4 = 2
To find the value of y when x = 1, we need to substitute x = 1 into the given equation y = 2x^3 - 4x.
Let's plug in x = 1 into the equation:
y = 2(1)^3 - 4(1)
Now, we can simplify the equation:
y = 2(1) - 4
y = 2 - 4
y = -2
Therefore, when x = 1, y = -2.
