Question

find the indicated outputs for f(x)=5xwith small 2 above - 2x
f(0)=
f(-1) =
f(2)=

Answer 1

????? cud not understand the given function....

Answer 2

i solved this way:
f(0) = 0
f(-1) = 5xwith small 2 -2x
f(-1)=5(-1)small2 -2(-1)
=5+2
=7
f(2)=5(2)small 2 -2(2)
=20-4
=16

Answer 3

so my answers are
0
7
16

Answer 4

pls use the equation box to type the question properly

Answer 5

where is equation box i'm new at this

Answer 6

is it
\[5x ^{2}/-2x\]

Answer 7

yes

Answer 8

look below the box in which you type answer. just below it u hv "Equation" and "Attach File" buttons side- be-side on the left...

Answer 9

k thnks

Answer 10

wait i am checking yr answers.......

Answer 11

except for first answers, other r wrong..
I'll show how it is to be done...

Answer 12

^2 means "raised to power 2"

5x^2
f(x) = --------
-2x
5 (0)^2 5 * 0 0
f(0) = -------- = ------ = ----- = 0
-2(0) 0 0

Answer 13

5 (-1)^2 5 * 1 5
f(-1) = -------- = ------ = -----
-2(-1) 2 2

and

5 (2)^2 5 * 4 20
f(2) = -------- = ------ = ----- = -5
-2(2) -4 -4

Answer 14

is it clear now how to do such sums???

Answer 15

yes it is now I had those other two answers but for some reason I did not stop there thank you and have a good morning

Answer 16

good morning to u too!!

Answer 17

however u were doing them wrong as for second u were getting 5+2 instead of 5/2

Answer 18

for third u were getting 20-4 =16 instead of 20/-4 = -5

Answer 19

when i worked them earlier I had 0, 5/2 and -5

Answer 20

anyway thanks for putting me back on track

Answer 21

given \[5x^2/-2x\] you should simplify first to -5x/2 and then input your numbers

Answer 22

yes that is an excellent suggestion by nobody.....
medal for him.....
