If there is any kind of suspicious mistake
then sorry
If it has no x-intercept, it is a horizontal line going through 0,-2. hope this helps
Answer:
Step-by-step explanation:
y = (x+1)² - 3
= (x²+2x+1)-3
= x²+2x-2
:::::
y = (x-2)² + 3
= (x²-4x+4) + 3
= x²-4x+7
Step-by-step explanation:
We will learn how to solve proportion problems. We know, the first term (1st) and the fourth term (4th) of a proportion are called extreme terms or extremes, and the second term (2nd) and the third term (3rd) are called middle terms or means.
Therefore, in a proportion, product of extremes = product of middle terms
example
1. Check whether the two ratios form a proportion or not:
(i) 6 : 8 and 12 : 16; (ii) 24 : 28 and 36 : 48
Solution:
(i) 6 : 8 and 12 : 16
6 : 8 = 6/8 = 3/4
12 : 16 = 12/16 = 3/4
Thus, the ratios 6 : 8 and 12 : 16 are equal.
Therefore, they form a proportion.
