If f(x) = 6x-11, what is f(-6)?​
In-s [12.5K]

If f(x) = (6x-11), then f(-6) = -47.

We are provided in the question statement with a function "f(x)" whose output is a polynomial of 1 variable and degree 1.

To obtain the value of f(-6) from the output polynomial of the function f(x), we will simply need to substitute (-6) as the value of x in the polynomial and calculate the final value.

So,

f(-6)=[(6*(-6))-11]\\or, f(-6)=(-36-11)\\or, f(-6)=-(36+11)\\or, f(-6) =-47

Hence, f(-6) = -47.

  • Polynomial: In mathematics, an expression of more than two algebraic terms, especially the sum of several terms that contain the same variable(s) of different powers and individual, distinct co-efficients.
  • Function: In Mathematics, a function is an operator which on taking input, provides a certain output.

Beginning in 2000, a sports team increased its ticket price by a constant amount each year until 2010.
Natalija [7]

Answer: $33

Step-by-step explanation:

The ticket cost $48 in 2005 and $57 in 2008 , the difference between the cost is

$57 - $48 = 9

it is said that it increased at a constant rate , that is it increased by 9 in three years which means it will increase by 3 per year.

the difference in years between 2005 and 2000 = 5 years.

The cost in the year 2000 = 48 - 3(5)

= 48 - 15

=33
