The standard form of a quadratic function is . The graph of quadratic function opens in the direction of the positive y-axis or negative y-axis, it depends on the coefficient of in the function. The shape of the graph of quadratic function is U shaped, because the greatest power of the x in the function is 2.
Hence The shape of quadratic function is U-shaped. It is the characteristics of the quadratic parent function.
They must be complementary. these 2 angles MUST equal 90 degrees because there is a right angle that is 90 degrees in the triangle already and all triangles have an angle sum of 180 degrees. the answer is complementary
