Question

Functions: Compute for f(x)=1/x
a. f(1/2)
b. f(1/10)
c. f(0.01)
d. f(0.007)
Not sure how to do it at all.

Answer 1

f(1/2) just replace x with 1/2

Answer 2

simplify 1/1/2 what do you get?

Answer 3

Uhh, I'm not sure. Having a really big brain fart. Would it be 1? Or?

Answer 4

\[\huge \frac 1{\frac 12}\]
do you know how complex fractions work?

Answer 5

Sounds Fimilar. But Not 100% Sure.

Answer 6

if you have something like \[\huge \frac 1{\frac 13}\]
you just take the reciprocal of 1/3 and multiply it to the numerator \[\huge \implies 1 \times \frac 31\]
got it?

Answer 7

So it would be 2?

Answer 8

yes

Answer 9

f(1/2) = 2

Answer 10

Okay, How would you do that with decimals?

Answer 11

turn them into fractions

Answer 12

How would you do that though? A 0.01 would be a 1/100? Or?

Answer 13

yes

Answer 14

And then a 0.007 would be a 1/700??

Answer 15

nope

Answer 16

7/1000
