How do I find the vertex for f(x) = 3x-7 and
The axis of symmetry for g(x)=3x+8

In the figure shown below, m < 40 and ab =8. which equation could be used to find x?

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

Will give brainliestbased on the topographic map of mt. st. helens, what is the contour interval if the volcano height is 2,950 m?
