Two functions are given below.
f(x) = −4x + 1 1
g(x) = −4x + 2
How does the graph of f compare with the graph of g?

• The graph of f is less steep than the graph of g.

•  The graph of f has the same y-intercept as the graph of g.

•  The graph of f is parallel to the graph of g.

• The graph of f is steeper than the graph of g.

Is the graph linear, exponential or neither?

• Linear

• Exponential

• Neither
