Question

Finding this function?

Answer 1

\[\frac{ f(a+h)-f(a) }{ h }\]

Answer 2

If H is \[\neq0\]

Answer 3

it goes with the main problem of

\[f(x)=6x-6\]

Answer 4

\[\frac{ 6a+6h-12+6a-6 }{ h }\]

is what I get

When cominging everything I get

\[\frac{ 6(2a+h-3) }{ h }\]

but the homework claims it is wrong any help?

Answer 5

You weren't careful with parentheses and minus signs.

Answer 6

\[\Large \frac{ 6(a+h) - 6 - (6a-6) }{ h }\]

Answer 7

THEN 6 IS THE ANSWER

Answer 8

YEP

Answer 9

Ah ok I was inputting the answers I had previously is why I mess up the format probably. What about this:

\[f(x)=x^2-x+14\]

\[f(-a)\]

I get

\[-a^2+a+14\]

and get that wrong?

Answer 10

(-a)^2 does not equal -a^2

Answer 11

just a?
or what am I missing?

Answer 12

What is (-2)^2?

Answer 13

Is it 4 or -4?

Answer 14

ah yes becuase -*- thanks
