a) Given:
[tex]k(x)=-x-3[/tex]
It is of the form, y=mx+c.
Comparing we get, m=-1. That is a negative slope.
So, the answer is
Line with a negative slope.
b) Given:
[tex]g(x)=-4x^2+1[/tex]
Since the quadratic function and its sign of the leading term is negative.
So, the answer is,
Parabola oppening down.
C) Given:
[tex]f(x)=3[/tex]
It is of the form, y=c.
Comparing we get, the y-intercept is c=3. It is parallel to the x-axis.
So, the answer is,
Horizontal line.
