what happens to the function f(x) = (x - 1)^2 + 1 when it becomes f'(x) = 1/2((x - 1)^2 + 1)?
it is compressed towards the x-axis
what happens to the function f(x) = (x - 1)^2 + 1 when it becomes f'(x) = 2((x - 1)^2 + 1)?
it is stretched away from x-axis
sarah enters the following into the cas. what did sarah do wrong?
she used "divide" instead of "division."
calculate the quotient. x^3 - 7x + 14 ÷ x + 4
x^2 - 4x + 9 - 22/x+4
calculate the quotient. 5x^7 − 18x^5 ÷ x^2 − 2
5x^5 - 8x^3 - 16x - 32x/x^2-2
consider the division problem. 9x^4 + 2x^3 ÷ x + 10 enter the division problem as you would in the cas tool.
Division(9x^4+2x^3,x+10)
what happens to the function f(x) = (x - 1)^2 + 1 when it becomes f'(x) = (2x - 1)^2 + 1?
XXX it is stretched away from the y-axis
