A quadratic function f is defined by /«) = (x - 7)(x + 3). a. Without graphing, identify the x-intercepts of the graph of f. Explain how you
know.
b. Expand (x - 7)(x + 3) and use the expanded form to identify the y-intercept of
the graph of 1

Its due ! write an equation in which the quadratic expression 2x^2-2x 12 equals 0. show the expression in factored form and explain what your solutions mean for the equation. show your work.

Find the measure of the missing angle

Wrong answers will be reported! (3,7), (10, 0), (2.5, 1)1. using the vertices of the feasible region you identified in #7, tell which of the vertices maximizes, and which minimizes, the following objective equation: p=8x+3y2. why do we often use x0 and y0 as constraints in a linear programming (optimization) problem?
