Work out the answers to:
a) 7 + (-4)
b) (-6) + (-3)
c) 2 -(-6)
d) (-8) - (-13)

a) 7 + (-4) = 3

b) (-6) + (-3) = -9

c) 2 -(-6) = 8

d) (-8) - (-13) = 5

Step-by-step explanation:

a) 7 + (-4)

= 7 + (-4)

= 3

b) (-6) + (-3)

= -6 - 3

= -9

c) 2 - (-6)

= 2 + 6

= 8

d) (-8) - (-13)

= -8 + 13

= 5

answer:

(-8,7)

explanation:

we know that  

f

(

−

3

)

=

7

therefore, if we wish to get the output as 7, in the function, we need to have our input to be -3.

looking at the function  

f

(

x

+

5

)

, what should the value of x be, such that the input in the function becomes 7?

we simply equate the terms,

x

+

5

=

−

3

x

=

−

8

thus, the point on the new function would be  

(

−

8

,

7

)

correct answer:

i^31 = -i
