Answer:
(0,5)
Step-by-step explanation:
Answer:
The vertex is at (0, - 5)
Solution
f(x) = x ^ 2 - 5 Identify the coefficients
a = 1, b = 0
Substitute the coefficients into the expression
x = - 0/(2 * 1)
Solve the equation
x = 0
Evaluate the function for x = 0
f(x) = x ^ 2 - 5, x = 0
Calculate the function value
f(0) = - 5
The vertex is at (0, - 5)
