Hi
Graphing: y = x^2 + 4x - 5
a)solutions: (1,0) and (-5,0)
b) Does this function have a maximum or a minimum? minimum
c) V(-2,-9)
d) x = -2 is the line of symmetry
{{{drawing(300,300,   -10,10,-10,10,blue(line(-2,10,-2,-10))  ,  grid(1),
circle(-2, -9,0.4),
graph( 300, 300, -10,10,-10,10, graph of y = x^2 + 4x - 5))}}}

Might recommend the following graphing software to use for checking
your work etc.
