Substitute values in the equation y = 1-3 to complete the table.
part a.
x(input) -2 ,-1 ,0, 1, 2
y(output) a, b, c, d, e
part b
is the above table a function?
a. yes, it is.
b. no, it is not

A.

a = -5

b = -4

c = -3

d = -2

e = -1

B. Yes. It is

Step-by-step explanation:

The given function is: y = x - 3.

Substituting the values for x, we get values of a,b,c,d,e.

Value of a: a = -2 - 3 = -5

Value of b: b = -1 - 3 = -4

Value of c: c = 0 - 3 = -3

Value of d: d = 1 - 3 = -2

Value of e: e = 2 - 3 = -1

The given function is y = x - 3

This is the equation of a line. Clearly it is a function.

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
