Given g(x) where f(x)= 3x-1 and g(x)= f(x+1). graph

The graph in the attached figure

Step-by-step explanation:

we have

we know that

To find out the function f(x+1) exchange the variable x for (x+1) in the function f(x)

so

therefore

using a graphing tool

see the attached figure

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
