Answer: f^{-1}(1)+f(-14)=20

f^{-1}(-2)=10  

Step-by-step explanation:

The given table :

x: -14,-7,-12,9,10,-2

f(x):11,-12,5,1,-2,13

Since f is invertible ( given) , then f^{-1}(x)  exists.

Now , from table f^{-1}(1)=9  [ x= 9 corresponding to f(x) =1]

f(-14)=11                            [ f(x) = 11 corresponding to x=-14]

then, f^{-1}(1)+f(-14)=9+11=20

So, f^{-1}(1)+f(-14)=20

Also, x= 10 corresponding to f(x) =-2, then

f^{-1}(-2)=10

-5+ 3= 2) -7 -4 3) 122 × (-9) 4) -6 divided by 3/4
lutik1710 [3]

Answer:

Step-by-step explanation:

1) -5 +3 = -2

When two numbers are in different sign, subtract and the result will have the bigger numbers sign.  The bigger number is 5. so the result is (-2)

2) -7 - 2 = -9

When two numbers have same sign, add and the result will have the common sign

3) 122 * (-9) = - 1098

4) -6 ÷ (3/4)

=(-6)*\frac{4}{3}\\\\=-2*4

= -8
