Question

The graph below shows three functions:

Graph of function f of x is a line segment connecting points negative 1, 11 and 4, negative 3. Graph of function g of x is a line segment with holes at the endpoints connecting negative 2, negative 4 and 0.5, 10. Graph of p of x equals 8 to the power of x.

Which function has all real numbers as its domain?

Answer 1

Only f(x)

Both g(x) and p(x)

Both f(x) and g(x)

Only p(x)
