The derivative, f'(x) = 6x^2+1, is never negative, so f(x) is monotonic, hence invertible.
f'(-2) = 6(-2)²+1 = 25
If point (-2, -26) is on the graph of function f(x), and the slope is 25 there, then (-26, -2) is on the graph of f⁻¹(x), and the slope is 1/25 there. The equation of the tangent line throught that point can be written in point-slope form as
... y +2 = (1/25)(x +26)
To make this table, pick any value you want for x, then substitute it an solve for y.
For example, if you choose x=1, then
y=-2/3(1)-1
y=-2/3-3/3
y=-5/3
To do a three part table quickly, I like to use -1, 0, and 1 for the value of x, since -1 and 1 will not change the values, only the sign for -1, and 0 eliminates the m section of the equation.
I hope this helps !!!!
