Identify the key features of these functions: f(x) = 3(x + 5)2 − 10 g(x) = -4x2 + 3x − 1 h(x) = -0.25(x + 3)(x − 1)

The construction of copying qpr is started below. the next step is to set the width of the compass to the length of ab. how does this step ensure that a new angle will be congruent to the original angle? by using compass take the measures of angle and draw the same arc according to it.
