Question

Could I get an explanation on what the answers are and why?

Answer 1

a) Given:

`k(x)=-x-3`

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:

`g(x)=-4x^2+1`

Since the quadratic function and its sign of the leading term is negative.

So, the answer is,

Parabola oppening down.

C) Given:

`f(x)=3`

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.
