Find the outputs for a given function using these input values: x: Input -10, 0, ,2 , 4, 10 Function Rule f(x) = -x+2 -10 0 2 4 10

12, 2, 0, -2 and 8

Step-by-step explanation:

Give the function f(x) = -x+2

If x = -10

y = -(-10)+2

y = 10+2

y = 12

If x = 0

y = -0+2

y = 2

If x = 2

y = -2+2

y = 0

If x  = 4

y = -4+2

y = -2

If x = 10

y = -10+2

y = -8

Hence the outputs are 12, 2, 0, -2 and 8

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.
