Answer:
Step-by-step explanation:
the sum of 5x+20= 5(x+4)
and the opposite of 20 is negtive 20
Represent any point on the curve by (x, 1-x^2). The distance between (0, 0) and (x, 1-x^2) is

To make this easier, let's minimize the SQUARE of this quantity because when the square root is minimal, its square will be minimal.
So minimize

Find the derivative of L and set it equal to zero.

This gives you

or

You can use the Second Derivative Test to figure out which value(s) produce the MINIMUM distance.

When x = 0, the second derivative is negative, indicating a relative maximum. When

, the second derivative is positive, indicating a relative MINIMUM.
The two points on the curve closest to the origin are
