The equation and the tables represent two different functions. Use the equation b=4a-5 and the table to answer the questions. This table represents C as a function of A.

A. When A is -3, is B or C greater?

B. When C is 21, what is the value of A? What is the value of B that goes with this value of A?

C. For what values of A do we know that C is greater than B?

Answer:

A) B is greater

B) when C = 21, A = 5 and B = 15

C) A must be 0, 5, or 12 for C to be greater than B

Step-by-step explanation:

A) when a = -3, c = -20 and b = 4(-3)-5 so B = -17

B) when c = 21, a = 5 and b = 4(5)-5 so B = 15

C) C is greater than B when a = 0, 5, and 12

when a = 0, b = 4(0)-5 or -5

when a = 5, b = 4(5)-5 or 15

when a = 12, b = 4(12)-5 or 43

The answer for option (A) is B is greater, option (B) is the value of B is 15 and A is 5, and option (C) is A must be 0, 5 or 12.

Function:

Function is a certain rule between domain and codomain. Domain and codomain is any set or subset of any set.

Here we have given that b = 4a -5 and a listed table for values of a and c where c is itself a function of a

Calculate b for given A = -3, and list out c form table

c = -20

b = 4(-3)-5 = -17

(A) Therefore B is greater than C

(B) When C is 21

The value of A = 5 and

The value of B = 4(5) -5 = 15

(C) For greater of C than B the required A is 0, 5 or 12

b = 4(0)-5 or -5 when a = 0

b = 4(5)-5 or 15 when a = 5

b = 4(12)-5 or 43 when a = 12
