4)
ordered pairs : (-5,4)(-3,2)(2,6)(-3,-5) it is not a function because it repeats x’s
5)
ordered pairs : (4,5)(2,5)(1,-3)(-2,-2) it is a function because it is NOT repeating x’s
6)
(2,6)(6,8)(6,10)(8,12) it is not a function because it repeats x’s
The inverse of a function will also be a function if it is a One-to-One function. This means, if each y value is paired with exactly one x value then the inverse of a function will also be a function.
Option C gives us such a function, all x values are different and all y values are different. So inverse of function given in option C will result in a relation which will also be a function.
In all other options, y values are being repeated, which means they are not one to one functions.
So, the answer to this question is option C
Answer:
The answer is 7.4 × 10³ ( or 0.74 × 10⁴).
Step-by-step explanation:
The steps are :
(1.5 × 10⁴) - (7.6 × 10³)
= (15 × 10³) - (7.6 × 10³)
= (15 - 7.6) × 10³
= 7.4 × 10³
The answer is x=-15/2
Im not sure how to explain it I’m sorry
