Question

For each function below, choose the correct description of its graph.line with aline

Answer 1

a)

`f(x)=x-1`

we have a linear function in this case the slope is equal to 1 therefore we have a line with a positive slope.

b)

`h(x)=2`

when the function is constant we will have a horizontal line

c)

`g(x)=3x^2+4`

we have a quadratic function and because the quadratic term is positive the graph will be a parabola opening up
