Answer:

Choice D is correct. Every x-value corresponds to exactly one y-value.

Step-by-step explanation:

We have given the set of ordered pairs :

{ (-5,-5) ,(-1,-2),(0,-2),(3,7),(8,9) }

We have to explain that is this set represent a function or not?

Function is a rule that assigns each input exactly one output.

In the set, each value of x has unique value of y.

From the definition of function,this set represent a function because each input has a single output.

Every x-value corresponds to exactly one y-value.

Answer:

D. Yes,because every x-value corresponds to exactly one y-value.

Step-by-step explanation:

The given ordered pairs are;

{(-5,-5),(-1,-2),(0,-2),(3,7),(8,9)}

We do not have the same x-value corresponding to more than one y-value.

We can see from the ordered pairs that every x-value corresponds to exactly one y-value.

Therefore the graph of this relation will pass the vertical line test.

Which equation can be simplified to find the inverse of y = 5x2 + 10?
zmey [24]

f^-1(x) = sq.rt 5(x - 10)/5, sq.rt 5(x - 10)/5 is the inverse of y = 5x^2 +10

Step-by-step explanation:

interchanging the variables

x = 5y^2 + 10

5y^2 +10 = x

5y^2 = x - 10

dividing by 5

5y^2/5 = x/5 + -10/5

y^2 = x/5 + - 10/5

y^2 = x/5 - 2

y = 5 (x-10) 0/5 (sq.rt)

g(5x^2 + 10) = 5x/5

g(5x^2 + 10) = x

f^-1(x) = sq.rt 5(x - 10)/5, sq.rt 5(x - 10)/5 is the inverse of y = 5x^2 +10

Use the discriminant to find the number of real roots in Y = x^2 – 6x + 9
BaLLatris [955]
So discriminant is being counted from that equation:
b^2-4ac = 36-36 = 0

As discriminant is 0, then there is just 1 root -> -b/2a = 6/2 = 3.
