Question

What is the Value of k(-6)

Answer 1

k x -6

Answer 2

You multiply

Answer 3

k(x)= x+14 if < - 7
21 if -7 <_ x < -6
x^2 -1 if x>_ -6

Answer 4

When you multiply a positive and a negative your always going to get a negative if it's a negative and negative it's always a positive.

Answer 5

Just solve for x

Answer 6

How??

Answer 7

if x = -6 then k(x) = x^2 - 1
so you just plug in x = -6 into x^2 - 1 and work it out.

Answer 8

that gives you k(-6)

Answer 9

so I have to go through each promblem working them out,,,
k(x)= x+14 if < - 7
21 if -7 x≤-6
x^2 -1 if x≥-6

Answer 10

no this is a step wise function
as you see the last line says that k(x) = x^2 - 1 when x is equal to or greater than -6
Here x = -6 so you only need to plug -6 into x^2 - 1.

Answer 11
