f(x) = 2 - 2x
f(-6)= 2-2(-6)
= 2+12
=14
f(0)= 2-2(0)
= 2-0
=2
f(1\2)= 2-2(1\2)
= 2-1
=1

Part I. Given the following function, y = f(x), find the indicated values:


a. f(1)
b. f(3)
c. f(0)





Part II. Given the function f (x) = – x2 + 7x - 22, find the indicated values:

a. f(3)
b. f(-3)
c. f(0)

Part I. Given the following function, y = f(x), find the indicated values: ...

"y= f(x)" does not define the function, so it's impossible to determine values.


Part II. Given the function f (x) = – x2 + 7x - 22, find the indicated values:

a. f(3)
b. f(-3)
c. f(0)

I assume the function is f(x) = x^2 +7x-22. For future reference note that we use the "^" symbol to mean "raised to the power of."

To find the value of a function you simply replace the 'x' with the value indicated in the parenetheses. Thus to find f(10) you replace the x with 10 and you get


f(10) = 10^2 + 7(10) -22 = 100+70-22 = 148.


Apply this method to determine the values for f(3), f(-3) and f(0).
