Question

Graph the function y=8- square root -2x+6. Which is the best approximation of a point on the function?

Answer 1

Answer:

D. {5.9,3.781}

Step-by-step explanation:

The equation of the function is given as;

$y=8-\sqrt{2x+6}$

You can use a graph tool to graph and view the graph;

From the graph attached, the point that gives a correct approximation of the function is : {5.9,3.781}

Using this in the equation, to test the coordinates will give;

3.781= 8-√{2*5.9 +6}

3.781 = 8 -√17.8

3.781 = 8-4.219

3.781 = 3.7809
