Evaluate f(-2) for the function f(x)= -1/2x^2 + x + 1

Answers

Answer:

f(-2) = -3

Step-by-step explanation:

[tex]f(x)=-\frac{1}{2} x^{2} +x+1[/tex]

Just plug in x = -2

[tex]f(-2)=-\frac{1}{2} (-2)^{2} -2+1[/tex]

[tex]f(-2)=-\frac{1}{2} (4) -1[/tex]

4 can be rewritten as [tex]\frac{4}{1}[/tex] or [tex]\frac{8}{2}[/tex] so it has a common denominator.

[tex]f(-2)=-\frac{1}{2} * \frac{8}{2} -1[/tex]

[tex]f(-2)=-\frac{4}{2} -1[/tex]

[tex]f(-2)=-2-1[/tex]

[tex]f(-2)=-3[/tex]
