Consider the function represented by 9x + 3y= 12 with x as the independent variable. How can this function be written using function notation?
O AD=-v
Of(x) = -3x+4
O POx) = -x +
O ft) = - 3y+4

For this one, you don't need to actually do any work.

Function notation is the f(x) or f(t) notation, but with function notation, the variable in the parentheses must match the variable on the right side of the equation.

f(a) = 2b+3 won't do any calculation because of the mismatched a and b.

Which answer is the only one with good function notation?

step-by-step explanation:

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
