Question

Answer 9 and 11 with explanation on how you solved it.

Answer 1

(9). Range; {8, 5, 2, -1, -4}

(10). Range; {-15, -7, 1, 9, 17}

Explanation:

Domain of a function is (x-values) determined by the input values and Range of a function is determined by the (y-values) output values of the function.

(9). For the given function,

f(x) = -3x + 2

If the Domain of this function is a set of values,

{-2, -1, 0, 1, 2}

For Range,

x -2 -1 0 1 2

f(x) 8 5 2 -1 -4

Therefore, Range of the function 'f' will be; {8, 5, 2, -1, -4}

(11). f(x) = 4x + 1

Domain is {-4, -2, 0, 2, 4}

Table for input-output values will be,

x -4 -2 0 2 4

f(x) -15 -7 1 9 17

Therefore, Range of the function will be {-15, -7, 1, 9, 17}
