Question

The table represents the function f(x).

x -9 -6 -3 0 3 6 9
f(x) 118 85 52 19 -14 -47 -80

If g(x) = 19 - 28x, which statement is true?

The graph of g(x) is steeper than the graph of f(x).
The graph of g(x) is less steep than the graph of f(x).
The graphs of f(x) and g(x) have the same steepness with negative slopes.
The graphs of f(x) and g(x) are both horizontal lines.

Answer 1

Notice that
\[
f(x) =19 -11 x
\]
