Please help what’s the domain and range

Answer & Step-by-step explanation:

The domain is the x values and the range is the y values.

Domain:

Note the lowest x values the line includes. Although it starts at x=2, it curves back to x=1 and then curves past 1. Therefore:

x is greater than or equal to 1.

Range:

Find the lowest y value that is included in the line. Since the line starts at y=-1 and only moves upward after then:

the y values are greater than or equal to -1.

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'.

-2 is the right
