Question

Graph the following quadratic functions. Find the x- and y-intercepts of each graph, if any exist. If it is given in general form, convert it into standard form; if it is given in standard form, convert it into general form. Find the domain and range of the function and list the intervals on which the function is increasing or decreasing. Identify the vertex and the axis of symmetry and determine whether the vertex yields a relative and absolute maximum or minimum. (a) f(x) = x^2 + 2 (c) f(x) = -3x^2 + 4x - 7 (b) f(x) = x^2 - 2x - 8 (d) f(x) = x^2 - x - 1

Step 1

Step 1:** For the function \( f(x) = x^2 + 2 \): - Axis of symmetry: \( x = 0 \) - Vertex: \( (0, 2) \) - X-intercepts: None - Y-intercept: \( (0, 2) \) - Domain: \( (-\infty, \infty) \) - Range: \( [2, \infty) \) - Increasing interval: \( [0, \infty) \) - Show more…
