Question

Graph the given function using the given values of x. Also use the graph to determine the domain and range of the function.

1a. f(x)=x^2+4 ; x = -3, -2, -1, 0, 1, 2, 3

Answer 1

$$f (x) = x ^ {2} + 4$$

the domain is R (the whole set of real numbers), range of the function $[4, +\infty)$ .
