Pls help ASAP on this question.

2. Tell whether or not each function is increasing or decreasing, and give the domain, range, and y-intercept of the function. a. y= 4 b. y= -3(4)* Increasing or Decreasing Increasing or Decreasing Domain - Domain - Range - Range - y-intercept - y-intercept -

Which statement(s) correctly describe y-intercepts? Which all apply? A. The y-intercept of a function is the point where the line intersects the y-axis. B. The y-intercept of a function is the point at which x = 0. C. The y-value of the y-intercept is the same as the starting value, b.

Graph the function: compare the graph to the graph of f(x)=|x|. Describe the domain and range

When nutrients for a bacteria culture are exhausted, the bacteria culture goes through the death, or decay, phase of the bacteria growth curve. The following graph shows the number of living bacteria in the colony as a function of time, in hours, after the start of the decay phase. Determine the statement that correctly interprets the graph of the function.

Exercises 77 and 78: Diagrams Complete the following. (a) Evaluate f(2). (b) Write f as a set of ordered pairs. (c) Find the domain and range of f. 77. 78. 2.

Determine whether the graph represents a function. Use the vertical line as a example
