Answer
a. 8, b. 2, c. 4
Work Step by Step
We are given the function $f(x)=x^{2}-3x+4$. In order to find the specified values, we can plug the values into the function and solve.
a. $f(-1)= (-1)^{2}-3(-1)+4=(-1\times-1)-3\times-1+4=(1)-(-3)+4=1+3+4=8$
b. $f(2)= (2)^{2}-3(2)+4=(2\times2)-3\times2+4=(4)-6+4=4-6+4=2$
c. $f(0)= (0)^{2}-3(0)+4=(0\times0)-3\times0+4=(0)-0+4=0-0+4=4$
