If f(x)=2/x-3 find f^-1(x)

Mathematics
1 answer:
cupoosta [38]3 years ago
4 0

Answer:

D

Step-by-step explanation:

To inverse a function, switch the y for x and x for y and solve for y

f(x) = 2/(x-3)

y = 2/(x-3)

x = 2/(y-3)

x*(y-3) = 2

y-3 = 2/x

y = 2/x-3

y = 2/x - 3x/x

y = 2+3x/x

Answer:

see explanation

Step-by-step explanation:

Given f(x) then the derivative f'(x) is

f'(x) = lim(h tends to 0 ) \frac{f(x+h)-f(x)}{h}

      = lim ( h to 0 ) \frac{4(x+h)^2-2-(4x^2-2)}{h}

      = lim ( h to 0 ) \frac{4(x+h)^2-2-4x^2+2}{h}

      = lim( h to 0 ) \frac{4x^2+8hx+4h^2-4x^2}{h}

      = lim( h to 0 ) \frac{8hx+4h^2}{h}

      = lim ( h to 0 ) \frac{4h(2x+h)}{h} ← cancel h on numerator/ denominator

      = lim ( h to 0 )  4(2x + h) ← let h go to zero

f'(x) = 8x

Lucy is knitting a blanket and needs to buy some more yarn. at her local craft store, 2 skeins of yarn cost $7 and 8 skeins of y
laila [671]

Answer:

4

Step-by-step explanation:

Proportionality between skein values

8:2=4:1

Proportionality between cost values

28:7=4:1

The variation(both the skein values and cost values) has the constant of 4 ie the 1st skein value × 4= the last skein value & the 1st cost value × 4=the last cost value
