Question

Find the range of the function for the values given. A merchant uses the rule f (c) = (4 × c) + 3 to set his selling price.

Answer 1

1 f(1) = 4(1) + 3 = 4 + 3 = 7

2 f(2) = 4(2) + 3 = 8 + 3 = 11

3 f(3) = 4(3) + 3 = 12 + 3 = 15

Explanation:

Answer 2

This question requires to find the values of the function f(c) = 4c + 3 for a set of c-values, but you forgot to include the set of c-values.

I am going to show you the procedure with an arbitrary set.

Assume the set is: c = {1, 2, 3}.

Then, what you must do is to enter the different values of c from that set and calculate the corresponding value of the function f(c).

This is how you do it:

c f(c) = 4c + 3
1 f(1) = 4(1) + 3 = 4 + 3 = 7
2 f(2) = 4(2) + 3 = 8 + 3 = 11
3 f(3) = 4(3) + 3 = 12 + 3 = 15

Therefore, for the given c-set, the range is {7, 11, 15}
