Write down the 1st term in the sequence given by: t(n) = n² - 4

first term = - 3

Step-by-step explanation:

To generate the first term in the sequence substitute n = 1 into the rule

T(1) = 1² - 4 = 1 - 4 = - 3

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

)

answer: 12
