The parents of a new baby believe they brought the wrong child home from the hospital. Gel electrophoresis was performed using DNA samples from the parents and the child. A section of the gel electrophoresis results is shown below. Which conclusion is valid based on the gel electrophoresis results?

What process does this picture show?

Solve the exponential equation. Use a calculator to obtain a decimal approximation, correct to two decimal places, for the solution.e x + 8 = 5

Find the domain of the logarithmic function.f(x) = log9(x + 1)2

Approximate the number using a calculator. Round your answer to three decimal places.21.7

Write the equation in its equivalent logarithmic form.3-3 =

Solve the exponential equation. Use a calculator to obtain a decimal approximation, correct to two decimal places, for the solution.e2x = 8

Find the domain of the logarithmic function.f(x) = log5(x – 2)2

Bonus. Worth up to 10 points.The function f is defined as f(x)= -x2-5.Find the difference quotient f(x + h) – f(x)h   for h not equal to zero. Show all work and simplify your answer as much as possible.

Show all work to justify your solutions. DO NOT JUST PUT THE ANSWERS. I want you to show me HOW you obtained your solution. If you only put answers, full credit may not be given. Use the Math Text Editor to type solutions using MATH TYPE, it is located in the TOOL BOX as a plus sign. If you decide to work these problems on your paper and take a picture to upload (like you have been doing on Quizzes), you may use the paper clip to attach. Attach as a jpeg or pdf.You may use a NON-graphing scientific calculator for the exam. A calculator is also provided inside HonorLock.HonorLock will tell you that you cannot use your phone. You CAN take pictures of your work AFTER you have worked the problems, so that you can upload your work, if you choose that route. Do NOT use Photomath, it is NOT a calculator.You have 2.5 hours to work this part of the Exam and upload your work. Good luck! Due by Sunday, May 5 by 11:59 pm CT. It will close at that time.DO NOT EMAIL ME YOUR WORK. If you have technical problems with HonorLock, make sure you send a message to them.
