Someone please help me I’m having trouble

(c) and

(d)

Step-by-step explanation:

Given

See attachment

First, we complete the table

So, we have:

Solving (c): Between which values is y

The values of y are for both equations are closest at:

and

Hence, the solution is between

and

Solving (d): Approximated value of the solution

We have:

So:

Collect like terms

Divide both sides by 3

Substitute in

So, the solution is:

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
