Question

2. Given f(x) = 6(8 - x)+5

Answer 1

Answer:

a) Find the value of the function when x  = -2

b) we get f(-2)=65

Step-by-step explanation:

We are given the function f(x)=6(8-x)+5

a) What does the notation f(-2) mean?

The notation f(-2) means that we have to put x = -2 in the given function of f(x) and find the value of the function when x  = -2

b) What is the value of f(-2) ?

We need to find the value of f(-2)

$f(x)=6(8-x)+5$

Put x = -2

$f(-2)=6(8-(-2))+5\\f(-2)=6(8+2)+5\\f(-2)=6(10)+5\\f(-2)=60+5\\f(-2)=65$

So, we get f(-2)=65
