t2 = 7 = 4* 2 - 1

t3 = 11 = 4 * 3 - 1

t4 = 15 = 4* 4 - 1

Answer:

The answer to your question is:

a)   f(a) -2 = a² - 3

b)    f(a - 2) = a² - 4a + 3

c)     f(b + d) = b² + 2bd + d² - 1

Step-by-step explanation:

a. f(a) - 2 = (a)² - 1 - 2

  f(a) -2 = a² - 3

b. f(a - 2) = (a - 2)² - 1

    f(a - 2) = a² - 4a + 4 - 1

    f(a - 2) = a² - 4a + 3

c. f(b + d) = (b + d)² - 1

   f(b + d) = b² + 2bd + d² - 1
