Question

find f(1) if.
f(x)=x^3+2x^2-x-1

Answer 1

Answer:

1

Step-by-step explanation:

f(x)=x^3+2x^2-x-1

f(1)=1^3+2(1)^2-1-1

f(1)=1+2*1-1-1

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

Answer 2

For given function, f(1) = 1

What is a function?

"It is an expression that defines a relationship between the independent variable and the dependent variable."

For given example,

We have been given a function f(x) = x³ + 2x² - x - 1

We need to find f(1)

Substitute x = 1 in given function.

⇒ f(1) = 1³ + 2(1)² - 1 - 1

⇒ f(1) = 1 + 2 - 1 - 1

⇒ f(1) = 1

Therefore, f(1) = 1
