Question

F(x)=x³
If x= -2, y =____
If x=-1, y =_____
If x = 0, y =____

Answer 1

Answers:

f(-2) = 8

f(-1) = 1

f(0) = 0

Explanation:

Evaluate f(-2) first.

Given function:

• 
  `\sf{f(x)=x^3}`

Substitute -2 for x:

`\sf{f(-2)=(-2)^3}`

`\sf{f(-2)=8}`

Substitute -1 for x:

`\sf{f(-1)=(-1)^3}`

`\sf{f(-1)=1}`

Substitute 0 for x:

`\sf{f(0)=0^3}`

`\sf{f(0)=0}`

Therefore, these are the answers:

If x= -2, y = 8.

If x=-1, y = 1

If x = 0, y = 0.
