MTH 220 Week 1 Checkpoint

Solve the following equation using the quadratic formula.

Evaluate the function at the given values of the independent variable and simplify.

Use the graph of f to determine each of the following.

(a) the domain of f

(b) the range of f

(c) the zero(s) of f

(d) f left parenthesis 4 right parenthesis

(e) the intervals on which f is increasing

(f) the intervals on which f is decreasing

(g) the values for which

f(x)less than or equals0

(h) any relative maxima or minima

(i) the value(s) of x for which f left parenthesis x right parenthesis equals 4

(j) Is f left parenthesis 3 right parenthesispositive or negative?

Give the slope and y-intercept of the line whose equation is given below. Then graph the linear function.

Use the given conditions to write an equation for the line in point-slope form and in slope-intercept form.

Find the average rate of change of the function

Use the graph of y =f (x) to graph the function

Begin by graphing the absolute value function, f (x)=|x|. Then use transformations of this graph to graph the given function.

For f(x)=x+4 and g(x)=2x+1, find the following functions.

The function f (x)=x^3-6 is one-to-one. Find an equation for f-1(x), the inverse function.

Find the distance between the pair of points.

Find the midpoint of the line segment whose endpoints are given.

Use a graphing utility with a viewing rectangle large enough to show end behavior to graph the polynomial function shown below.

Use the seven step method described in the book to graph the following rational function.
