slope
What is the slope of a line that passes through points (2, 2) and (6, 3)?
1/4
Solve 12x + 8 + 3x + 38
x = 6
what is a many-one function?
More than one element in the domain set has the same f-image
Solve 4 < x + 1 < 10
3 < x < 9
Solve - 8 + 5x = 2 + 7(9 - 3x)
x = 2.81
What is the slope of a line that passes through points (-2, 0) and (0, -2)?
-1
Solve 2x - 65 + 3x = 45
x = 42
What's a into function?
When the co-domain of the function is not equal to the range of function, that is, a few elements in the co-domain set does not have a pre-image in the domain set.
Solve 4 < 2x - 1 <= 10
5 < x < 11
Solve 5 + 2x = 5x - 2x
x = 5.00
What is the slope of a line that passes through points (-7, 8) and (5, -7)?
-5/4
Solve 9(x - 3) = 27
x = 6
What is a onto function?
Every element of the co-domain set of the function has a pre-image in the domain set.
Solve - 10 <= 2x - 1 <= - 4
- 4.5 <= x - 1.5
Solve 3x + 4 = - 9(- 5x + 5)
x = 1.17
What is the slope of a line that passes through points (3, 2) and (4, -9)?
-11
Solve 3x - 16 * 4x + 5
x = 3
What's a one-to-one function?
Every single element of the domain set has different f-images.
Solve - 20 < 4x - 2 <= 8
- 4.5 < x <= 2.5
Solve - 3(7 + 3x) = - 7(8x - 4)
x = 1.04
What is the slope of a line that passes through points (5, -5) and (-6, -4)?
-1/11
Solve 8(x - 2) = 6
x = 4
What's a bijective function?
A function which is both one-one and onto.
Solve - 10 <= 4x - 2 <= 4
- 2 <= x <= 1.5
Solve 3(3x - 6) = 4x + 7
x = 5.00
