Question
Write simplified form for each of the following. Be sure to list all restrictions on the domain, as in Example 5.$$g(t)=\frac{21-7 t}{3 t-9}$$
Step 1
The numerator, 21-7t, can be factored as 7(3-t). The denominator, 3t-9, can be factored as 3(t-3). Now we can rewrite the expression as: g(t) = (7(3-t))/(3(t-3)) Show more…
