Answer:
The evaluation is [tex]f(-2)=-4[/tex]
Step-by-step explanation:
We were given an explicit function of x, wich has the form
[tex]f(x)=x^2+4x[/tex]
The problem ask to evaluate f(-2), this means to put the value x=-2 into the function, so
[tex]f(-2)=(-2)^2+4(-2)=4-8=-4[/tex]
Therefore, the answer is
[tex]f(-2)=-4[/tex]
