Points are

  • (-4,-1)
  • (-2,1)
  • (1,-2)
  • (4,-4)
  • (2,4)

All x values has a unique image in y so it's a function

\\ \sf\longmapsto D_f=\{-4,-2,1,4,2\}

\\ \sf\longmapsto R_f=\{-1,1,-2,-4,4\}

Answer:

<u>The domain is the set of x-values:</u>

  • {-4, -2, 1, 2, 4}

<u>The range is the set of y-values:</u>

  • {-4, -2, -1, 1, 4}

This can be a function as each x- value has exactly one corresponding y- value.

Task 5:
Natasha_Volkova [10]

Answer:

p=18x+4

a=20x^2+17x-63

a=1350

Step-by-step explanation:

Given:

l=5x-7

w=4x+9

Required:

Area of the rectangle=?

Perimeter of the rectangle=?

If x = 9 inches what is the area of the shape=?

Formula:

a=l*w

p=2(l+w)

Solution:

p=2(l+w)

p=2(5x-7)+2(4x+9)

p=10x-14+8x+18

p=10x+8x+18-14

p=18x+4

a=l*w

a=(5x-7)(4x+9)

a=20x^2+45x-28x-63

a=20x^2+17x-63

Area of the shape if x=9in

a=20x^2+17x-63

a=20(81)+17(9)-63

a=1620+153-63

a=1413-63

a=1350
