How do I solve this?

A quadratic function fis given. ((x) = x2 - 4x + 5 (a) Express fin standard form. f(x ) = (b) Find the vertex and x- and y-intercepts of f. (If an answer does not exist, enter DNE.) vertex ( x, y ) = ( x-intercept (x, y ) = ( y-intercept (x, y ) = ( (c) Sketch a graph of f. Graph Layers After you add an object to the graph you can use Graph Layers to view and edit its properties. -10 Helo (d) Find the domain and range of f. (Enter your answers using interval notation.) domain range
