Answer:
B
Step-by-step explanation:
Given focus as (h,k) and directrix as y = mx + b, the equation of a parabola is given as:
Hence, from the given focus & directrix, we have:
h = -1
k = -1
m = 0
b = 1
<em>We can plug them into the formula and arrange to get:</em>

<em>B is the correct answer.</em>
It will cost 3.5*1.8 which 3 * 1.8 is 5.4 and then add .5 of 1.8 which is 0.9 and 5.4+.9 is 6.3 dollars.
X+2.5
or X+7.5
or 5x+ 2.5
or 5x+7.5

Answer:
Step-by-step explanation:
Given is a function f(x)
We have to analyse and sketch the graph
X intercept : Put y =0, we get x=0
Y intercept: Put x =0 , we get y =0
No exception for x or y and hence set of all real numbers is domain and range.
f' becomes 0 not at finite points
So relative extreme
Graph is sketched and attached
