Please help today is my birthday !!! part A: Without using a graphing calculator, which equation could be represented by the accompanying graph?

Question 10 options:

y=2^x

y=2−x

y=x^2−2

y=−2^x

Part B: Explain how you selected the equation in Part A

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.  

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)

y=sec x is the correct answer
