The curve y=x³ is translated by p units, parallel to the x axis. State the equation of the curve after it has been transformed
y = (x - p)³ (given that p > 0 in the positive x direction and p < 0 in the negative x direction)

y = x^2 + 7x + 3. At P, x = 0, so y = 3, and P is (0,3) dy/dx = 2x + 7. whilst x = 0, dy/dx = 7, so the gradient of the tangent to the curve at (0,3) is 7, so the equation of the tangent to the curve is y = 7x + c whilst x = 0, y = 3, so 3 = 0 + c, so c = 3, and the equation of the tangent to the curve at P is: y = 7x + 3.

You're shifting the whole thing up or down the y axis by p units so it's
y = x^3 + p

before the translation,
the equation is
y=x^3
after the translation,
if the graph shifted p
units in the x +ve
direction,the equation is
y=(x-p)^3
after the translation,
if the graph shifted p
units in the x -ve
direction,the equation is
y=(x+p)^3
{note:if you want to shift
the graph p units in the y +ve
direction,the equation is
y=x^3+p
if you want to shift
the graph p units in the y -ve
direction,the equation is
y=x^3-p}
i hope that this helps
