A company is selecting students for interviews at the career fair. The number of students selected from university A is given by f (x) = 4x + 5, where x represents the number of days of the fair. The number of students selected from university B is given by g (x) = 2x + 8. Which function best describes the total number of students selected at the career fair?

a. h (x) = (4x + 5) (2x + 8)

b. h (x) = 2x - 3

c. h (x) = - 2x + 3

d. h (x) = 6x + 13

Allison · Answer 1

Number of students selected from University A:

f (x) = 4x+5

Number of students selected from University B:

g (x) = 2x+8

So total number of students selected from both universities:

h (x) = f (x) + g (x)

Put values

h (x) = 4x+5+2x+8

h (x) = 6x+13

Option D is correct.
