ANSWER
When x=1, is 2
and is 2
When x=2, is 8
and is 4
EXPLANATION
The given functions are:
and
We want to find the functional values for the given x-values.
When x=1,
and
When x=2,
The first function gives us:
and the second function gives
QUESTION 1
The given function is
We simplify to get;
This function is equal to zero when
QUESTION 2
The given function is
We factor to get;
This function equals zero when
QUESTION 3
The given function is
We factor to get,
The function equals zero when
Hence the equation has no real roots.
The complex roots are
or
They do.
According to the Pythagorean theorem:
c² = a² + b²
In a right triangle, the longest side is actually a hypotenuse: c = 25
a = 7
b = 24
25² = 7² + 24²
625 = 49 + 576
625 = 625
Therefore, <span>the side lengths form a Pythagorean triple</span>
