If you horizontally stretch the quadratic parent function, f(x) = x2, by a factor of 4, what is the equation of the new function
navik [9.2K]
Please write x^2, not x2.

If you stretch the graph of y=x^2 vertically by a factor of 4, the resulting graph represents the quadratic function y = 4x^2.  It's still a parabola, but appears to be thinner.

This particular question is about horizontal stretching, however.  Stretching the graph horizontally by a factor of 4 results in the new function g(x) = (x/4)^2.  Try graphing x^2 and also (x/4)^2 on the same set of axes to observe this phenomenon.

AfilCa [17]

Answer:

p = 250 - 15(w)

Step-by-step explanation:

Original amount: 250

No of weeks to return money:  w

Amount to pay each week: 15  

Amount that he has paid back: 15 × w  (When we subtract this term from the total we will get the answer)

So after w weeks he owes his parents :

p = 250 - 15(w)

HELP!!!!
m_a_m_a [10]

Answer:

(0,0)

Step-by-step explanation:

The coordinates of C now are (-7,-5).

Moving C -3 on the x-axis will move -7 - 3 = -10. C is now located on (-10,-5).

Moving C +5 on the y-axis will move -5 + 5 = 0. C is now located on (-10,0).

Moving C on the y-axis +10 will move -10 + 10 = 0. C is now located on (0,0).

C is translated to (0,0).
