Answer 2

I got..

3x^2 -12x+11

Correct? Or did I miscalculate some where?

Answer 3

oops you forgot to post the question

Answer 4

Sorry -10x not -12x ...

Answer 5

26. Evaluate the function at the given value of the independent variable and simplify.

f(x) = 3x2 - 4x + 4; f(x - 1)

Answer 6

oh right, the prev one

Answer 7

Yes lol.

Answer 8

I'm not getting 3x^2 - 10x + 11

Answer 9

Hmmm..

Answer 10

Are you sure its wrong?

Answer 11

yes I'm sure

Answer 12

I checked my calculations and it seems to be correct.. Its listed as an option. And mathway says its right..

Answer 13

what is (x-1)^2 equal to?

Answer 14

3(x-1)^2 -4(x-1)+4
3(x^2 -2x+1) -4x+8
3x^2 -6x+3-4x+8
3x^2 -10x +11

Answer 15

(x-1)^2 is x^2 -2x+1

Answer 16

hmm I typed it into my calc wrong, my bad

Answer 17

3x^2 - 10x + 11 is correct

Answer 18

Lol its okay.

Answer 19

For this next one I got to the last step but Its not shown as an option...

Find and simplify the difference quotient f(x+h)-f(x) over h , h=/ 0.
f(x)= 3x^2

I got 6x+3h

Answer 20

same here

Answer 21

The only option that is close is 3(2x+h) so I guess thats it?

Answer 22

that works

Answer 23

Okay.
