Question

Let F(x) be the function 4x^2-7x+4. Then the quotient [F(6+H)-F(6)]/h
can be simplified to for: Ah + B. How do I simplify this? My text book doesn't cover it... oddly enough Let F(x) be the function 4x^2-7x+4. Then the quotient [F(6+H)-F(6)]/h

Answer 1

what are your outcomes for F(6) and F(6+h)

Answer 2

and theres something missing between to and for

Answer 3

Ah, Ah + B is suppose to be between to and for , then following For is What is A= and B =

Answer 4

So i should just input 6+h and 6 into the polynomial? But how do I know what is Ah and what is B?

Answer 5

A = 8 and B = -7 but thats what we should get to

Answer 6

yes

Answer 7

I think its spose to read Ax + B

Answer 8

different notation, I have seen it as Ax as well.

Answer 9

4(6+h)^2-7(6+h)+4 - (4(6)^2-7(6)+4)

4(6+h)^2-7(6)+7(h)+4 - 4(6)^2+7(6)-4

4(6+h)^2+7(h) - 4(6)^2

4(36 + 12h +h^2)+7(h) - 4(6)^2

4(36) + 48h +4h^2+7h - 4(36)

48h +4h^2+7h
------------- = 48 + 7 + 4h
h

i spose it does work out to hs

Answer 10

the 6 is what thru me off i think

Answer 11

my math is off i think ... gotta dbl chk it

Answer 12

After I do the computation how do i know which is Ax or B? Without knowing the rule, its ambiguous to me haha

Answer 13

should be a -7

Answer 14

the one with the h by it is the Ah part, and the one that stands alone is the B part

Answer 15

just match the given pattern with what your results look like and equate the numbers

Answer 16

yeah, i missed a sign up top; -*+ = - and i got +

Answer 17

so 56 + 4h from the example you gave earlier a= 56 and B = 4? or am I jumping the gun

Answer 18

48-7+4h is what it should be, i missed one of my signs in the process

Answer 19

so we get 41 + 4h = Ah + B

Ah = $h

41 = B

Answer 20

cant type ....

Answer 21

4h = Ah
41 = B

so, A = 4 and B = 41

Answer 22

ah okay cool, thanks man!
