Question

math@@@

Answer 1

\[f^{-1}(x) \]
^this represents the inverse of the function f(x)

so basically u need to find the inverse function of the function f(x) which is given to us

:)

do u knw how to find the inverse of any function?

Answer 2

i don't know nothing bro

Answer 3

its ok
i'll tell u hw to do that
its not at all difficult

Answer 4

u have this-
f(x)=7x+12

here f(x) is y

so
y=7x+12


1st step to find out the inverse is to isolate x
y=2x+12
y-12=2x+12-12
y-12=2x
(y-12)/2=2x/2
(y-12)/2=x

So now we have isolated x

2nd and the last step is to switch x with y and y with x
(y-12)/2=x
(x-12)/2= y

here y is- \[f^{-1}(x)\]

so we now have our inverse function as-\[f^{-1}(x)=\frac{ x-12 }{ 2 }\]

Answer 5

do you know what the sinx is?

Answer 6

bro

Answer 7

tel me about this man

Answer 8

\[sin(x) = \frac{opposite}{hypotenuse}\]

so \[sin(38) = \frac{24}{x}\]\[x = 24.sin(38)\]

Answer 9

yeah solve that one bro

Answer 10

i need help with this one now

Answer 11

clearly B. A doesn't have a bar for 62

Answer 12

right
