1-use the vertex and intercepts to sketch the graph of the quadratic function. give the equation of the parabola's axis of symmetry. use the graph to determine the domain and range of the function.
f(x)=(x+4)^2−9
2-
a. graph
f left parenthesis x right parenthesis equals negative x squared minus 4 xf(x)=−x2−4x
by determining whether its graph opens up or down and by finding its vertex, axis of symmetry, y-intercept, and x-intercepts, if any.
b. determine the domain and the range of the function.
c. determine where the function is increasing and where it is decreasing
