Answer:
Step-by-step explanation:
1. take out constants
( 5 × 2 × 4 × - 4 × - 2)
2. simplify 5 × 2 to 10
(10 × 4 - 4 × - 2)
3. simplify 10 × 4 to 40
(40 × - 4 × - 2)
4. simplify 40 × -4 to -160
(-160 × - 2)
5. simplify -160 × -2 to 320
6. use product rule:
7. simplify 5 + 5 to 10
8. simplify 10 + 5 to 15
Answer:
We have to determine the graph of the given inequality as:
on solving this equation we get:
Since we know that:
Now we know that when the value of:
Also for the value other than -1 the function being a quadratic function will always give a non-zero positive value.
Hence, range of the function in intervals could be written as:
(-∞,-1)∪(-1,∞).
Hence, the graph of the function will be the whole of the number line with a open circle on -1.
