A student finds the slope Of the line between (8, 17) and (1, 4). A.) She mixed up the x- and y-values.

B.) She should have added the values, not subtracted them.

C.) She did not keep the order of the points the same in the numerator and the denominator.

D.) She used y-values where she should have used x-values.

C.

Step-by-step explanation:

The slope formula is y2-y1/x2-x1.

The student in the problem did more like y2-y1/x1-x2.

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1

x = 3 ± √(5+y)
