What the composite function in the question is actually trying to explain is;
First of all, in the function , we will find a result by writing
where we see the letter
.
We will write this result in the function where we see the letter
and we will get the result.
Answer:
A) base = 6 units
B) height = 4 units
C) Area = 24 square units
Step-by-step explanation:
Base on the gragh given,
The base = |-5| + |1| = 6 unit
The height = |2| + |-2| = 4 unit
The area = base × height
The area = 6 × 4 = 24 square units.
Answer:
The answers A,B,D and E are verified.
Explanation:
We have equation, x⁴ - 3 x² + 2 = 0
Substituting y = x²
So equation is y²- 3 y+ 2 = 0
=> (y-1)(y-2) = 0
y = 1 or y = 2
So we have x² = 1 or x² = 2
=> x = 1 , x = -1 , or
So the answers are A,B,D and E.
