The product of 3/4 and 7/8 is less than 7/8

Yes, it is correct.

Step-by-step explanation:

When we multiply a positive real number by a positive real number less than 1,

Then the value of the original number is always decreased,

Here,

Also,

Thus, by the above statement,

Verification :

Since, the product of and is,

= 0.65625 < 0.875

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.
