Question

Determine the value(s) for which the function f(u)=−9u+8/−12u+11 is undefined. If there's more than one value, list them separated by a comma, e.g. u=2,3. Enter integers or fractions if necessary.

Answer 1

To determine the values for which the function f(u) = (-9u+8)/(-12u+11) is undefined, we need to find the values of u that make the denominator (-12u+11) equal to zero.

Step-by-step explanation:

To determine the values for which the function f(u) = (-9u+8)/(-12u+11) is undefined, we need to find the values of u that make the denominator (-12u+11) equal to zero.

To find these values, we set the denominator equal to zero and solve for u:

-12u+11 = 0

-12u = -11

u = -11/-12

Therefore, the function f(u) is undefined when u = 11/12.
