If we have that the function is f(x) = 7x - 4, and the domain is {-1, 0, 2, 5}, we can find the range substituting each of the values of the domain in the function to get the range. Then, we have that:
F(-1) = 7*(-1) - 4 = -7 - 4 ---> F(-1) = -11.
F(0) = 7* (0) - 4 = 0 - 4 ---> F(0) = - 4.
F (2) = 7 * (2) - 4 = 14 - 4 ---> F(2) = 10.
F( 5) = 7 * (5) - 4 = 35 - 4 ---> F(5) = 31.
Therefore, the range for the function with this domain is R = {-11, -4, 10, 31}.
