Question

If y2 = 2x + 1 , which value appears to be the solutions to Y1=Y2

Select each correct solution

A : x = -4

B : x = -3

C : x= -2

D : x = 1

E : x = 1.5

F : x = 1.75

G : x = 3

Answer 1

Answer: (d) and (e)

Explanation:

Given

The function is
`y^2=2x+1`

It can be written as
`y=\pm √(2x+1)`. So, the domain of the function is

`\Rightarrow 2x+1\geq 0\\\\\Rightarrow x\geq (-1)/(2)`

So, for every value of x greater than -0.5. The function has two values of y.

Thus, option (d) and (e) are correct.
