Domain : (- ∞, - 5), and (3 / 2, ∞),

Range : (∞, 0.4437]

Step-by-step explanation:

Assuming that we want our answer in interval notation, let's start by determining the domain. Remember that the domain can be found where the function is undefined.

Given : f(x) = (2x - 7) / (2x² + 7x - 15)

Alternative Form : (2x - 7) / (x + 5)(2x - 3)

To receive this 'alternative form' we can simply factor the expression 2x² + 7x - 15. See the procedure below,

Now let's find the domain using the expression '(x + 5)(2x - 3) = 0.' If the denominator equals 0, the function is considered undefined.

Knowing these solutions the domain has the intervals (- ∞, - 5), and (3 / 2, ∞). The range is the set of values that correspond to the domain, so in this case the range would be (∞, 42 + 8√17 / 169]. 42 + 8√17 / 169 = (About) 0.4437, so it lies on the interval (∞, 0.4437].

The images below represent the plotted function in two areas. There are 3 curves in this graph.

it's 100

step-by-step explanation:

22, 28, 34, 40, 46

b)   f(n) = 6n + 16

  n = what is the number of the row ( 22 would be row 1) so if we replaced n with 1, we would get 22

c)   the  14th  row will have 100 seats

(1)   (2)   (3)   (4)   (5)   (6)   (7)   (8)   (9)   (10) (11) (12) (13) (14)

22 | 28 | 34 | 40 | 46 | 52 | 58 | 64 | 70 | 76 | 82 | 88 | 94 | 100
