Answer 1

Option A

Explanation:

From the piecewise function given in the picture,

f(x) = k³ + x If x < 3

=
`(16)/(k^2-x)` If x ≥ 3

Here, function is discontinuous at x = 3

If the function is continuous at x = 3 then,

k³ + 3 =
`(16)/(k^2-3)`

(k³ + 3)(k² - 3) = 16

k⁵ - 3k³ + 3k² - 9 = 16

k⁵ - 3k³ +3k² - 25 = 0

By using a graphing tool we can get the point where k = 2.081.

Option A is the answer.
