# If The Function Y=3 - 2x Is Shifted Right 1 And Down3 What Is The Resulting Function Show Work .

Given the function f(x) = x^3 + x^2 − 2x + 1, what is the resulting function when f(x) is shifted to the left 1 unit?

f(x) = x³ + x² − 2x + 1

// To shift this function 1 unit to the LEFT,

// you need to replace x by (x+1)

// (Look at the 3 sample graphs of y=x² below)

f(x+1) = (x+1)³ + (x+1)² − 2(x+1) + 1

f(x+1) = (x+1) [(x+1)² + (x+1) - 2] + 1

f(x+1) = (x+1) [x² + 2x + 1 + x+1 - 2] + 1

f(x+1) = (x+1) [x² + 3x] + 1

f(x+1) = x³ + 3x² + x² + 3x + 1

f(x+1) = x³ + 4x² + 3x + 1.................ANS

please help. sorry this is so much! studying for my final.

Write the function whose graph is the graph of y=x^3, but is shifted to the right 2 units?

y = (x-h)^2 +k

h is shifting on the x axis and k is the shift on the y axis

The graph of y= - sqrt(x) is shifted 4 units up and 3 units right. What equation represents the new graph?

To get the graph 4 units up just add 4 to y.... To get the graph 3 units right just subtract 3 to x...

Then equation of the new graph is y = - sqrt(x-3) + 4 OK!

How would I transform the function y=2^x to obtain the graph of y=2^(x+1)-3?

a million. it really is genuine because countless his non one hundred innings were a key to achievements for community indian community. 2. extremely bogus because it became good right into a unforgettable move with and a commonly used of its style. 3. certainly because he has achieved above 450 suits and it may extremely effect his universal in spite of the actual incontrovertible truth that it maintains to be precise above 40 8. 4. certainly. Indians count number selection on him lots. 5. could be. it really is complicated to declare. really he has achieved more beneficial suits so for effective he could have more beneficial reward to his call. 6. similar recommendations because the fifth. 7. likely now not. there are really some more beneficial complicated recreation enthusiasts than him. 8. i don't believe of of so. He has were given many distinct fowl ans man or woman huge selection rankings. 9. till eventually 2008. Then there became good right into a blinding style of competition. Sehwag, Gambhir, Yuvraj, Dhoni and now Kohli. yet he's truly a tale. 10. confident. because till eventually Nineteen 1890s now not many ODI mathces were achieved. He and ODI have began at the same time.
