Without sketching the graph of the function, find the maximum value of y = - 5x + 4 over the interval - 4 < = x < = 3. explain how you found this value.

Step-by-step explanation:

Given function is linear function. This linear function represents the straight line on the coordinate plane. The slope of this line is Since the slope is negative, the linear function is decreasing for all x. This means

You ar geven the interval So, the maximum value of the function is at the point x=-4 and the minimum value of the function is at the point x=3.

At x=-4,

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'.

the answer will be b x² +x-1
