Answer: The required value of the expression at x = 0 is 7.
Step-by-step explanation: We are given to evaluate the following expression for x = 0.
[tex]g(x)=7+(-4x^2)~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
To evaluate, we must substitute x = 0 in the given expression.
So, putting x = 0 in equation (i), we get
[tex]g(x)\\\\=7+(-4x^2)\\\\=7-4x^2\\\\=7-4\times 0^2\\\\=7-0\\\\=7.[/tex]
Thus, the required value of the expression at x = 0 is 7.
