The range is {-37,-25,-13,-1}. So you need to figure out what four numbers from this list of numbers (1,2,3,4,5,6,7,8), when applied to this function, ( f(x)=-6x+11 ), equals these numbers that are in the range {-37,-25,-13,-1}.
So you apply each of these numbers (1,2,3,4,5,6,7,8) into the function (f(x)=-6x+11) one by one.
f(1)=-6(1)+11=5 f(2)=-6(2)+11= -1 f(3)=-6(3)+11= -7 f(4)=-6(4)+11= -13 f(5)=-6(5)+11= -19 f(6)=-6(6)+11= -25 f(7)=-6(7)+11= -31 f(8)=-6(8)+11= -37 As you can see, f(2),f(4),f(6),and f(8) equal the numbers that are in the range {-37,-25,-13,-1}.
Negative Exponent Rule: this says that negative exponents in the numerator get moved to the denominator and become positive exponents. Negative exponents in the denominator get moved to the numerator and become positive exponents. Like this||
