Question

What value of x makes the denominator of the function equal zero? y= 6/4x-40

Answer 1

Y=6/(4*10)-40
y=6/40-40
y=6/0
undefined

Answer 2

To find the value that would make the denominator equal to zero, set the denominator equal to zero and solve for x.
4x - 40 = 0
Add 40 to both sides.
4x = 40
Divide both sides by 4
x = 10
