If g(t) = 2/(t + 3), then g() = 2/(4a + 3).
stiks02 [169]

Answer:

g(4a) = \frac{2}{4a + 3}

Step-by-step explanation:

Given the function is g(t) = \frac{2}{t + 3} ........... (1)

Now, we are given that g() = \frac{2}{4a + 3} .......... (2)

Now, the left hand side of both the above equations (1) and (2) are similar and the only change is that t is replaced by 4a.

Therefore, the equation (2) can be written as  

g(4a) = \frac{2}{4a + 3} (Answer)

Since we know that if g(t) = \frac{2}{t + 3} then g(k) = \frac{2}{k + 3}, where k is any real value.
