Answer:
k = 1
Step-by-step explanation:
Given that,

If (x+1) is a factor of (x), we need to find the value of k.
Using remainder theorem to find it.
Put (x+1) = 0
x = -1
Put x = -1 in equation below.

So, the value of k is 1.
The cube root of a number is the number which when multiplied by itself three times give you the original number. ... The square root of a number is the number which when multiplied by itself twice give you the original number. As an example, the square root of 9 is 3 because 3×3 = 9
Answer:
21/4
Step-by-step explanation:
Rate of change also means slope.
Pick any two points, for example (8,167) and (12, 188)
Now use the formula y2-y1/x2 - x1 to find slope
188 - 167/ 12 - 8
21/4
The rate of change is 21/4, <em>note you would NOT convert the fraction into to a decimal until your teacher specifies you to.</em>
F(-1) is the inverses of an equation so plug in y for x.
