Mathematics
1 answer:
n200080 [17]2 years ago
6 0

Step-by-step explanation:

the domain of a function is the interval or set of valid values for x (the input variable).

y = -x²

has no limitations for x. any value from -infinity to +infinity is possible and valid.

so, the domain is (-infinity, +infinity).

please consider the round brackets, because infinity is not a valid value and is therefore not included in the interval.

Determine the vertex of the function f(x) = 2(x − 5)2 + 8.
choli [55]

Answer:

Vertex ( 5 ,8) .

Step-by-step explanation:

Given  : f(x) = 2(x − 5)² + 8.

To find : Determine the vertex of the function .

Solution : We have given

f(x) = 2(x − 5)² + 8.

Vertex form of parabola  : f (x) = a(x - h)² + k, where (h, k) is the vertex.

On comparing f(x) = 2(x − 5)² + 8. with vertex form of parabola.

a = 2 , h = 5 , k = 8 .

Vertex ( 5 ,8) .

Therefore, Vertex ( 5 ,8) .
