Question

Функція задана формулою f(x)=x2-3 знайти f(0)-f(-1)​

Answer 1

f(x) = x² - 3

f(0) = 0² - 3 = - 3

f(- 1) = (- 1)² - 3 = 1 - 3 = - 2

f(0) - f(- 1) = - 3 - (- 2) = - 3 + 2 = - 1

Ответ : - 1

Answer 2

To find the value of f(0) - f(-1), we first need to calculate the values of f(0) and f(-1) using the given function f(x) = x^2 - 3.

Step 1: Calculate f(0) To find f(0), we substitute x = 0 into the function: f(0) = 0^2 - 3 f(0) = -3

Step 2: Calculate f(-1) To find f(-1), we substitute x = -1 into the function: f(-1) = (-1)^2 - 3 f(-1) = 1 - 3 f(-1) = -2

Step 3: Find f(0) - f(-1) Now, we can subtract the two values we found in Step 1 and Step 2: f(0) - f(-1) = (-3) - (-2) f(0) - f(-1) = -3 + 2 f(0) - f(-1) = -1

So, f(0) - f(-1) is equal to -1.
