Lamar made $35,000 in taxable income last year. Suppose the income tax rate is 15% for the first $8500 plus 17% for the amount over $8500.
How much must Lamar pay in income tax for last year?

?

Ithink is a. true, but not sure

Idon't see any graph, however the graph of the function : f(x) = x²-2x+3 is a parabola: 1) open upward (since a> 0)2) it intersects y-axis in 3 (y=3)3) its axis of symmetry is x = +1 ( -b/2a)4) it's minimum is y = -2, so its vertex is (1,-2)5) it doesn't intersect the x-axis since discriminant < 0
