Consider the quadratic function. f(x) = (x+4) (Jr1) (a) What g the xintercepts and rm? (b) What is the equation of the axis of symmetry? (c) What are the coordinates of the vertex? (d) Graph the function on the coordinate plane. Include the axis of symmetry. y= - ( x+ 4 ) ( ox - ) - - (m 2 3+ ( - 4 ) 2 ( on+ 3 ) " + 25 met ?
