Find (a) the axis of symmetry and (b) the vertex of the graph of the function.
Ax) = 4x² - 8x

Roger and natalie travel in similar cars. roger's car drives the two miles to school in 7.5 minutes. natalie drives the same distance in the opposite direction but in only 6.5 minutes. what is true of their velocities?

Consider that lines b and c are parallel. what is the value of x? what is the measure of the smaller angle?

Will give brainliest b. describe the function over each part of its domain. state whether it is constant, increasing, or decreasing, and state the slope over each part.
