Question

Can someone help me??!

Answer 1

When you compare two functions f(x) and g(x), you're looking for a special input $x^\ast$ such that

$f(x^\ast)=g(x^\ast)$

Since you have the table with some possible candidates for $x^\ast$, you simply have to choose the row that gives values for f(x) and g(x) that are as close as possible (the exact solution would give the same value for f(x) and g(x), so the approximate solution will give values for f(x) and g(x) that are close to each other).

In your table, the values for f(x) and g(x) are closer when x=-0.75

Answer 2

Answer:

From the table an approximate root is -0.75.

Step-by-step explanation:

The values of the 2 sides of the equation are closest when x = -0.75. The exact root is between -0.75 and -1.
