Piecewise Defined Function, take a look at the picture below.

  f(1) = -1

Step-by-step explanation:

The first step is to identify the applicable "piece" of the piecewise function. For x=1, it is the middle piece.

The second step is to put the argument value where x is and do the arithmetic.

  f(1) = -1² = -(1)(1)

  f(1) = -1

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~

there should be an link icon on the bottom of the text box you get. it looks like a paperclip!
