Answer
a. 2, b. -10, c. -4
Work Step by Step
We are given the function $f(x)=x^{2}-5x-4$. In order to find the specified values, we can plug the values into the function and solve.
a. $f(-1)= (-1)^{2}-5(-1)-4=(-1\times-1)-5\times-1-4=(1)-(-5)-4=1+5-4=2$
b. $f(2)= (2)^{2}-5(2)-4=(2\times2)-5\times2-4=(4)-(10)-4=4-10-4=-10$
c. $f(0)= (0)^{2}-5(0)-4=(0\times0)-5\times0-4=(0)-(0)-4=0-0-4=-4$
