Answer
a. See Graph Below, -4.011
b. -4.011, they are the same
Work Step by Step
$f(x)=x^{2}+ 1.79x - 3.21$
a. See Graph Below
According to the graph the minimum point of the function is at (-0.895, -4.011)
Thus the minimum value is -4.011
b. $f(x)=x^{2}+ 1.79x - 3.21$
$f(x) = x^2 + 1.79x + 0.895^2 - 3.21 - 0.895^2$
$f(x) = (x+0.895)^2 - 4.011025$
Thus the minimum point of the function is at (-0.895, -4.011025), which is equivalent to that of part a.
