Given the following linear function sketch the graph of the function and find the domain and range.
ƒ(x) = -5x + 4

.

Step-by-step explanation:

(The graph is attached)

Remember that the domain is the set which contains all the values that x can use. In this case, the x can use all values possible, therefore, we say that the domain is all Real Number Set.

Similarly, the range is the set which contains all values that y can use. In this case, the y can use all values possible. Therefore, the range is .

Generally, all linear functions have this domain and range because they don't have any special restriction like rational or irrational functions.

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

i did it myself and i got 4.2 (b) hope its right
