Iwill give you 35 points if you me cheat. for each of the equations below, determine wether the given value is a solution or not. it’d be greatly appreciated if someone would me with the others as well.. so i can pass my math

(if f(x)=4x^2 and g(x)=x+1, find (f o g)(x)

Suppose a least-squares regression line is given by modifyingabove y with caret equals 4.302 x minus 3.293. what is the mean value of the response variable if xequals20?

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
