This is a bit harder. I suggest getting the Domain and Range for the function of x.
If any of these answers have, an infinite domain and (3, infinite) range. That will be your answer.
Your answer is B.
f(x) = 2x²+3 has the same domain and range as x²+3
The answer is D. 100%
Markup is the amount added to the total cost of product to cover the total overheads and profit.
In markup based on selling price method, the selling price is considered as the endpoint that companies wanted to achieve, (100%) and the markup will be adjusted to cater into thaat equation.
X = 30 because the ratio of 27/45 = .6 so 18/.6 is 30
< ABD + > ABC = 180.....because these angles form a linear pair
2x + 5x + 5 = 180
7x + 5 = 180
7x = 180 - 5
7x = 175
x = 175/7
x = 25
< ABC = 5x + 5......5(25) + 5 = 130 <==
write question properly bro
