Answer:
Given the statement: if y =3x+6.
Find the minimum value of
Let f(x) =
Substitute the value of y ;
Distribute the terms;
The derivative value of f(x) with respect to x.
Using
we have;
Set
then;
By zero product property;
and 2x + 3 = 0
⇒ x=0 and x =
then;
at x = 0
f(0) = 0
and
x = -1.5
Hence the minimum value of is, -5.0625
=========================================================
One method is to plot the points P(3,6) and Q(7,3) on the same xy grid. Plot a third point R at (3,3). See the diagram below.
A right triangle forms in which we can find the legs PR = 3 and RQ = 4. The hypotenuse is found through the pythagorean theorem.
a^2+b^2=c^2
3^2+4^2 = c^2
9+16 = c^2
c^2 = 25
c = sqrt(25)
c = 5
This is the length of PQ

Or you can use the distance formula which is effectively using the pythagorean theorem just in a slightly different format (though it may not be obvious).
