ANSWER
C. 28
EXPLANATION
The given expression is
[tex] {x}^{2} - 7x + 10[/tex]
We want to evaluate this function at x=-2.
We just have to substitute x=-2 into the given expression.
In other words, we have to replace x with -2 wherever we see x in the expression
[tex]{( - 2)}^{2} - 7( - 2) + 10[/tex]
We evaluate the exponent to get
[tex]4 - 7( - 2) + 10[/tex]
We multiply next to get:
[tex]4 + 14+ 10[/tex]
We now add to obtain:
[tex]28[/tex]
The correct answer is C
