Answer 5

The initial value is -12

so plug that into the function to get ???

Answer 6

that all is clear
like how to plug in and get the ans

Answer 7

but the problem is that -12 is also the first iterate?

Answer 8

f(x) = 2x + 10

f(-12) = 2(-12) + 10

f(-12) = ???

Answer 9

-14

Answer 10

so is -14 the first iterate?????

Answer 11

-12 is the first (that's given)

-14 is the next iterate

Answer 12

to get the third iterate, plug in x = -14

Answer 13

so it is D ?

Answer 14

yes and I recommend you compute the rest of the iterates for practice

Answer 15

oh
thanks a lot
