Question

express the relation given by the equation represent y as function of x . if x²-y=25​

Answer 1

Answer:

x-5=y

x+5=y

Step-by-step explanation:

x2 - y = 25

x2 - 25 = y

x2 - 52 = y

(x - 5) (x + 5) = y

so, x-5=y

x+5=y

Answer 2

Y=x^2-25 is the answer. We name equation y so y becomes function of x. Value of y will depend on value of x.
