given f(x)= -3/4x-6 and its domain: (-8, 0, 4) what is the range of the function?
Question
Answer:
The range of function is { 0, -6, -9}Solution:Given that the function is:[tex]f(x) = \frac{-3}{4}x - 6[/tex]Also given its domain is (-8, 0, 4)To find: Range of the functionDomain of the function is possible input of the function that is "x" and range of the function is possible output of the function that is f(x) As there are only three input values for "x" that are (-8, 0, 4) we can determine the range by calculating value of f(x) for each of the xFor x = 8:[tex]f(-8)=\frac{-3}{4} \times(-8)-6=6-6=0[/tex][tex]f(-8)=0[/tex]For x = 0:[tex]\begin{array}{l}{f(0)=\frac{-3}{4} \times(0)-6=-6} \\\\ {f(0)=-6}\end{array}[/tex]For x = 4:[tex]\begin{array}{l}{f(4)=\frac{-3}{4} \times(4)-6=-3-6=-9} \\\\ {f(4)=-9}\end{array}[/tex]Thus the range of function is { 0, -6, -9}
