Does there exist a function that is not a relation

1 answer:

4 0

No, a function is always a relation. A relation may not always a function but the vice versa is true.

It's like the relationship between a rectangle and a square. A rectangle has 4 right angles and 2 sets of congruent sides while a square has 4 right angles and all sides are congruent. Which means that a rectangle is a square, but a square may not always be a rectangle.

How to solve. Y=-4(x-2)squared+4

Amiraneli [1.4K]

What do you mean, "solve"?
y = -4(x-2)² + 4
the line is a parabol with a maximum (2;4)
it's roots are -4(x-2)² + 4 = 0 => (x-2)² = 1 => x-2 = 1 => x = 3
=> x-2 = -1 => x = 1
symetrical axe: x = 2
is that all you need?
