Find the function value, if possible. (If an answer is undefined, enter UNDEFINED.) f(x) =

−5x − 5, x < −1
x2 + 2x − 1, x ≥ −1
(a)
f(−4)

(b)
f(−1)

(c)
f(1)

  (a) 15

  (b) -2

  (c) 2

Step-by-step explanation:

For each given value of x, determine the applicable function definition and use that to determine the function value.

-4 is less than -1, so the first function definition applies:

  f(-4) = -5(-4) -5 = 20 -5

  f(-4) = 15

__

-1 is equal to -1, so the second function definition applies:

  f(-1) = (-1)^2 +2(-1) -1 = 1 -2 -1

  f(-1) = -2

__

1 is greater than -1, so the second function definition applies:

  f(1) = (1)^2 +2(1) -1 = 1 + 2 -1

  f(1) = 2

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
