Find the functional values f(-2), f(0), and f(1) for the function. ƒ(x) = X²- 1
To find the functional values f(-2), f(0), and f(1) for the function ƒ(x) = x² - 1, you simply substitute the given values of x into the function and evaluate.
1. f(-2):
Substitute x = -2 into the function:
ƒ(-2) = (-2)² - 1
ƒ(-2) = 4 - 1
ƒ(-2) = 3
Therefore, f(-2) = 3.
2. f(0):
Substitute x = 0 into the function:
ƒ(0) = (0)² - 1
ƒ(0) = 0 - 1
ƒ(0) = -1
Therefore, f(0) = -1.
3. f(1):
Substitute x = 1 into the function:
ƒ(1) = (1)² - 1
ƒ(1) = 1 - 1
ƒ(1) = 0
Therefore, f(1) = 0.
So, the functional values for the function ƒ(x) = x² - 1 are:
f(-2) = 3
f(0) = -1
f(1) = 0.
