Question

Find all values x = a where the function is discontinuous.f(x) = 8x^2 + 8x + 4.

Analyzing functions

Find all values $$x = a$$ where the function is discontinuous.
$$\displaystyle{f{{\left({x}\right)}}}={8}{x}^{{2}}+{8}{x}+{4}.$$

Given function $$\displaystyle{f{{\left({x}\right)}}}={8}{x}^{{2}}+{8}{x}+{4}$$
$$\displaystyle{x}\in{R}$$, so
