What represents the inverse of the function f(x)=4x

Yuki888 [10]

Answer:

$\frac{x}{4}$

Step-by-step explanation:

The given function is

f(x) = 4x

As we know

f(x) = y, which implies x= $f^{-1} (y)$

Therefore,

y = 4x

x = $\frac{y}{4}$

as x= $f^{-1} (y)$

So,

$f^{-1} (y) = \frac{y}{4}$

replacing y by x in the above expression

$f^{-1} (x) = \frac{x}{4}$

So our inverse function is $\frac{x}{4}$

Sue has saved $54 more than Bill

Step-by-step explanation:

Given

Sue saves $5 a week. so after 36 weeks he will have

= 36 * 5

= $180

Bill's saving is modeled by

m = 3.5w where w is the number of weeks

After 36 weeks,

$m = 3.5 * 36\\=126$

The difference between savings of Bill and Sue

$= 180-126\\=54$

Hence,

Sue has saved $54 more than Bill
