Two functions are shown in the table below.

Function 1 2 3 4 5 6
f(x) = −x2 + 4x + 12
g(x) = x + 8

Complete the table on your own paper, then select the value that is a solution to f(x) = g(x).
x = 3
x = 4
x = 5
x = 6

welshfella · Answer

just plug in the values into the 2 functions and put them into the table

welshfella · Answer

e. g.  for f(x)
x = 3  = -3^2 +4*3 + 12 = -9 + 12 = 15

g(x)
x = 3:-   g(3) =  3 + 8 = 11

welshfella · Answer

note f(3) and g(3) are  a short way of saying the values of f(x) and g(x) when x = 3

welshfella · Answer

when x is a value such that f(x) = g(x)  that is the solution
