Huh? Is their a picture or anything else that goes with that question?
Answer:
(See explanation below for further details).
Step-by-step explanation:
Let be a parametric curve represented by 
and 
, where 
is the parametric variable.
The curve is represented graphically with the help of a graphing tool, whose outcome is included in the image attached below. The corresponding rectangular equation is found by eliminating t of each equation.
and 
The parametric equations represents a linear function (first-order polynomial).
Answer:
I think it's C. Sorry if it's incorrect! I worked it out in like 2 min.
Hello.
Simply plug -1 into 2x+2.
f(x) = 2x +2
f(-1) = 2 (-1) +2
f (-1)= -2+2
f(-1) = 0
Hope this helped.

Answer: 12%
Step-by-step explanation:
Let the original salary be Rs a
Salary after increase = a + 40% of a
= a + 40a/100
= 140a/100
= 14a/10
= 7a/ 5
Salary after Decrease = 7a/5 - 20% of 7a/5
= 7a/5 - 20× 7a / 100 × 5
= 7a/5 - 7a/25
= ( 35a - 7a) / 25
= 28a/25
Absolute increase = 28a/25 - a
= 3a/25
Percentage = 3a/25 ×100 / a
= 3 × 4
= 12%
