SOLUTION: Find the vertex, axis of symmetry, x and y intercepts, y min or y max, domain and range then graph. y=2x2^-9x+7 Y intercept: set x=0 2(0)2^-9(0)+7 = 7 ??????

Question 1056263: Find the vertex, axis of symmetry, x and y intercepts, y min or y max, domain and range then graph.
y=2x2^-9x+7

Y intercept: set x=0 2(0)2^-9(0)+7 = 7 ??????

Yes, the y-intercept is (,).
Complete the square and convert to vertex form,

So the vertex is (,),
axis of symmetry is ,
Since , the parabola opens upwards so the vertex value is the minimum,
.
Domain is all reals.
Range is [,).
