the graphs of functions f and g are shown below.
a) find all values of x for which f(x)=g(x).
b) find all values of x for which f(x) c) find all values of x for which f(x)> g(x).

a) x=0, x=-10, x=11

Step-by-step explanation:

Just find the x- coordinates for when f(x) intersects g(x).

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'.

i belive those are the ones that are under 90 degreese.
