The value of the given quadratic function m(x) at [tex]x = -3[/tex] is - 3.
"A quadratic function is one of the form [tex]f(x) = ax^{2} + bx + c[/tex], where 'a', 'b', and 'c' are numbers with a not equal to zero."
Given quadratic function is [tex]m(x) = x^{2} + 4x[/tex].
For [tex]x = -3[/tex], the value of the given function is
[tex]m(-3)\\= (-3)^{2}+4(-3)\\= 9 - 12\\= -3[/tex]
