Determine f^-1(2) given the following: f(1 = -3f(2) = -2f(-1) = 2f(3) = -1

lana [24]

We assume that the function is as follows:

$f^{-1_{}}(2)=?$

Then, we have that:

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

Thus, if we have that:

$f(2)=-2\Rightarrow f^{-1^{}_{}}(x)=\frac{1}{f(x)}\Rightarrow f^{-1}(2)=\frac{1}{f(2)}=\frac{1}{-2}\Rightarrow f^{-1}(2)=-\frac{1}{2}$

Therefore, the value for the function is f^-1(2) = -1/2 or

$f^{-1}(2)=-\frac{1}{2}$

13 out of 60 people surveyed were left handed calculate the angle you would use in a pie chart

PtichkaEL [24]

Total angle for the pie chart = 360°

13 out of 60 = 13 / 60

Angle for it = 13 / 60 * 360 = 13 * 6 = 78°

Angle used = 78°

Which situation could be solved using the equation -4+4=0

navik [9.2K]

we are supposed to explain

Which situation could be solved using the equation $-4+4=0$

As we can see in the given equation , one number is -4 and the other number is 4

When we add two number of same value but opposite in sign we get zero.

This equivalent to the real life situation of paying a post paid bills.

Suppose you are using a post paid service , and the bills gets generated at the end of the month.

Suppose the bills amount is $x.

Once you pay that bills , then total outstanding again becomes $0.

Because $-x+x=0$
