Answer:
It's 0.61
Step-by-step explanation:
I graphed the equation and got 0.61 on the x axis when the y value was 1.24
The missing x-coordinate is 9.5. The correct answer is option D.
A function in mathematics set up a relationship between the dependent variable and independent variable. on changing the value of the independent variable the value of the dependent variable also changes.
The given function [tex]y = 2 -\sqrt{x+1}[/tex] and the point are ( x, -1.24 ). Put y = -1.24 in the given equation to get the value of x.
[tex]y = 2 -\sqrt{x+1}[/tex]
[tex]-1.24 = 2 - \sqrt{x+1}\\-1.24 - 2 = \sqrt{x+1}\\-3.24 = \sqrt{x+1}[/tex]
Squaring on both sides.
[tex](-3.24)^2 = (\sqrt{x+1})^2[/tex]
10.5 = x + 1
x = 9.5
Hence, the correct option is D.
