The range is the difference between the lowest number and the highest number.
If x was the lowest number, then the highest number shown is 49
X = 49- 58 = -9
If x was the highest number, the lowest number given is 3
X = 3 + 58 =61
The two values would be -9 and 61
The graph of f(x) = g(x) would be the same as y = x graph ...
Where slope is 1 and the vertex is (0,0)
Let the number be x.
2*(x-4) < (x+5).
2x -8 < x +5
2x-x < 5 +8
x<13.
The number is less than 13.
That's it. Cheers.
No, a function is always a relation. A relation may not always a function but the vice versa is true.
It's like the relationship between a rectangle and a square. A rectangle has 4 right angles and 2 sets of congruent sides while a square has 4 right angles and all sides are congruent. Which means that a rectangle is a square, but a square may not always be a rectangle.

40 divided by 5 is 8 so after 8 classes
