The function y = f (x) is linear. Given f-¹ (0) = 3 and f (1) = - 4, find the formula of
f (x) and f-¹ (x)

Step-by-step explanation:

Using slope-intercept form of linear function:  

Find inverse of slope-intercept form:

swap x and y:  

Make y the subject:

Equate the equations and solve for :

Substitute found value for into one of the equations and solve for :

Substitute found values of and into equations for and :

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'.
