An expression in logarithmic form, such as log2(32), is read, “the log, base 2, of 32.” To evaluate log expressions, think of the exponent: log2(32) = 5, because the exponent needed for base 2 to become 32 is 5. An equation in logarithmic form is equivalent to another equation in exponential form, as shown below.

Identify the form of a quadratic function that immediately reveals a given feature of that function. Features in question are the y-intercept of the graph, the zeroes ("roots") of the function, and the vertex of the parabola. In Lessons 22 and 23, students produce equivalent forms of quadratic expressions by completing the square to reveal properties of quadratic functions (A-SSE.3). Students use the skill of completing the square again in Geo.6, Lessons 5 and 6, to write given equations of circles in standard form and to identify the center and radius of the circle ... Nov 17, 2020 · If the parabola opens upward, your answer will be the minimum value. If the parabola opens downward, your answer is the maximum value. In this example, since the parabola opens upward, f(-1.25) = 0.875 is the minimum value of the function.
