No, the first one you did get correct but the second, third and fourth are wrong here is you correct answer. F(x) = 4x - x to the second power So you substitute x for the numbers under x. The second answer under f(x) is wrong it’s suppose to be... F(x) = 4(0) - 0 to the second power the answer is 0. The third answer under f(x) is also wrong the answer is... F(x) = 4(-1) - -1 to the second power the answer is -3. Looking back I see that under x the number 2 in f(x) is wrong also. The answer Is f(x) = 4(2) - 2 to the second power equals 4.
