Which of the following equations best represents the graph of a function f(m)?

f(y) = m

f(x) = m

y = f(m)

x = f(m)

What is the vertex form of f(x) = x2 + 6x + 3

The table below shows the height of a ball  x  seconds after being kicked.  what values, rounded to the nearest whole number, complete the quadratic regression equation that models the data? f(x)  =  x2  +  x  +  0based on the regression equation and rounded to the nearest whole number, what is the estimated height after 0.25 seconds?   feet

Solve the following simultaneous equation by using an algebraic method (either substitution or elimination) 2x + 3y=-4 4x-y=11
