Answer:

see explanation

Step-by-step explanation:

Since p(x) = x² + 2 , if x ≤ 4

For x = 4 then this is included in the inequality x ≤ 4

whereas x > 4 does not include x = 4 but values greater than 4

Thus to evaluate x = 4 use p(x) = x² + 2

A cell phone plan costs $39 a month. The plan includes 2 gigabytes (GB) of free data and

DerKrebs [107]

a) C(0.5) = 39, C(2) = 39, C(4) = 69

b) Answers in part (a) represents the values of C at x = x₀

c) C(x) is continuous at x = 2

C (x) = 39 for 0 ⩽ x ⩽ 2

Since x = 0.5 is in the range 0 ⩽ x ⩽ 2:

C(0.5) = 39

Since x = 2 is in the range 0 ⩽ x ⩽ 2

C(2) = 39

Since x = 4 is in the range x > 2

C(4) = 39 + 15(x - 2)

C(4) = 39 + 15 (4 - 2)

C(4) = 39 + 15(2)

C(4) = 39 + 30

C(4) = 69

b) The answers in part A represents C(x). That is, the values of C at x = x₀

c) Is C(x) continuous at x = 2

C(2) = 39

$\lim_{x \to 2} C(x) = 39$

Since $\lim_{x \to 2} C(x) = C(2)$ , the function C(x) is continuous at x = 2
