b
Step-by-step explanation:
i just graphed each of them and b was the one that look most similar
Since y varies with x, the same we do to y, applies to x.
x = 4 y=7
x= 4*3 = 12
x= 7*3 = 21
Therefore, x = 21
Final answer: x=21 and y= 12
End behavior of a polynomial function is based on the <u>degree of the function</u> and the <u>sign of the leading coefficient</u>.
<u>Sign of the Leading Coefficient</u> determines behavior of right side:
- Positive: right side goes to positive infinity
- Negative: right side goes to negative infinity
<u>Degree of the function</u> determines the behavior of the left side:
- Odd degree: left side is opposite direction of right side
- Even degree: left side is same direction as right side
If you have an expression in the denominator, then you must divide the denominator into the numerator. The result will have a degree and a leading coefficient. Use the rules stated above to determine the end behavior.
For example:
y = 
We can factor to get: y = 
y = x + 3
Leading Coefficient of y = x + 3 is positive so right side goes to positive infinity.
Degree of y = x + 3 is odd so left side is opposite direction of right side, which means left side goes to negative infinity.
The denominator may not divide evenly into the numerator thus leaving a remainder, but that is ok. We can still use the rules stated above.
98.
The numbers increase by intervals of 8. You need 16 more terms until you reach the 20th term, so 16*8=128.
128-30=98.
