115. Which is the equation of a quadratic function with x-intercepts
(-5,0) and (1,0)?
a. y=x2 - 4x - 5
b. y = x2 - 4x + 5
c. y=x2 + 4x - 5
d, y = x2 + 4x + 5

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.
