Describe the error in the work shown. a small submarine starts at –1,260 feet in relation to sea level. then it descends 5 feet per minute for 12 minutes. what is the new position of the submarine in relation to sea level? –1,260 + (–5)(12) = –1,260 + 60 = –1,200

°°°°°°°°°°°°°°°°°°°°°°°°°°

-1,260 + (-5)(12) = -1,260 + 60

Step-by-step explanation:

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

)

no, x cannot be the same number. in all of them, x is 1. for one input there is another output. g is not a function
