Answer
a. -4, b. 14, c. 0
Work Step by Step
We are given the function $f(x)=x^{2}+5x$. In order to find the specified values, we can plug the values into the function and solve.
a. $f(-1)=(-1)^{2}+5(-1)=(-1\times-1)+5\times-1=(1)+5=1-5=-4$
b. $f(2)=(2)^{2}+5(2)=(2\times2)+5\times2=(4)+10=4+10=14$
c. $f(0)=(0)^{2}+5(0)=(0\times0)+5\times0=(0)+0=0+0=0$
