Answer:
Some functions repeat forever (sine and cosine) and those functions are known as periodic functions.
The period goes from from any point to the next matching point or one peak to the next peak.
The mid line or center line is a horizontal axis about which the graph of a periodic function oscillates.
The amplitude is the height from the mid line to the peak .
Answer:
5 x (7x²-3)
5 (7x²-3)
Step-by-step explanation:
Product means the result of multiplication.
Difference means the result of subtraction
Times indicates multiplication
square of means raised to the power of 2
The product of 5 and the differenceof 7 times the square of x and 3
5 x (7x²- 3)
When you see "and" in between, this indicates the variables that are involved in the operation mentioned. Since it says the product of 5 and the difference of... This mean that 5 is multiplied to the quantity of the other operation used, which is the difference of 7 times the square of x and 3.
