Question

If you have a constraint that you can sub. in Ex: xz=1 into f=yz+xz Revise

a) xz = 1
b) yz + xz = 1
c) yz = 1
d) yz + xz = f

Answer 1

The substitution process involves replacing xz with 1 in the function f = yz + xz, resulting in the revised function f = yz + 1.

Step-by-step explanation:

The student is asking how to substitute the constraint xz = 1 into the function f = yz + xz. The process involves replacing the occurrence of xz in the function with the given constraint that xz equals to 1.

Steps for substitution:

1. Start with the given function f = yz + xz.
2. Substitute the value of xz from the constraint xz = 1 into the function.
3. Replace xz in f = yz + xz with 1. This results in f = yz + 1.

As a result, f = yz + 1, which means that f depends on the variable yz and the constant 1 added to it.
