Range = {-2(-2) - 5, -2(-1) - 5, -2(1) - 5, -2(2) - 5} = {4 - 5, 2 - 5, -2 - 5, -4 - 5} = (-1, -3, -7, -9}

Answer:

{-1, -3, -7, -9} is  the range of the function f(x)

Step-by-step explanation:

Domain is the set of all complete possible values of x variable.

Range is the set of all values of f(x)

Given the function:

f(x) = -2x-5        .....[1]

Domain: {-2, -1, 1, 2}

For x = -2,

Substitute in [1] we have

f(-2) = -2(-2)-5 = 4-5 = -1

Similarly ,

For x = -1

f(-1) = -2(-1)-5 = 2-5 = -3

For x = 1:

f(1) = -2(1)-5 = -2-5 = -7

For x = 2

f(2) = -2(2)-5 = -4-5 = -9

Therefore, the range of f(x) = {-1, -3, -7, -9}

Factor x^2+6x-16 into the form (x+a)(x-b), what is a and b?
vfiekz [6]

Answer:

a=-8 b=2

Step-by-step explanation:

x^2+6x-16

x^2+(8-2)x-16=0

x^2+8x-2x-16=0

X(X+8)-2(X+8)=0

(X+8)(x-2)=0

Compare with (X+a)(X+b)

Where we get a=-8 b=2
