Answer:
The graph has only one x-intercept
Step-by-step explanation:
we have
we know that
The discriminant of a quadratic equation of the form
is equal to
in this problem we have
so
substitute
The discriminant is zero
That means ----> The quadratic equation has one real solution
The graph has only one x-intercept
Answer:
Step-by-step explanation:
To find the values of for which, the value of
belongs to
,we solve the inequality;
We multiply through by 8 to obtain;
We subtract 3 to get
Divide through by -1 to obtain;
Or
Answer:
A) The functions are not inverses of each other.
Step-by-step explanation:
The result of f(g(x)) is not always x, so the functions are not inverses of each other.
In general, a quadratic (or any even-degree polynomial) such as g(x) cannot have an inverse function because it does not pass the horizontal line test.
