The correct answer is any value greater than 21/4 (or 5.25) and less than 27/5 (or 5.4). If -9/5 < -3 x + 1 < -7/4 what is one possible value of 9 x - 3? AP college board SAT practice problems The next question is considered “easy,” requiring the learner to use fractions/decimals (if they choose) to solve an inequality: A calculator table could be used to find the function, or the two possible choices could be graphed, and the resulting table would confirm that choice D shows population doubling after a time (x-value) increase of 12.ģ. The first two choices are linear, so since the question says “the population will DOUBLE…”, which implies an exponential answer, eliminate them. This requires creating a linear function to represent a real-world scenario. The following is considered “easy” in difficulty. Assume that the domain of a given function is the set of all real numbers.ġ.Figures are drawn to scale unless told otherwise. All variables and expressions are real numbers unless otherwise noted.General directions for this section you should expect to see: Select a graph that matches a nonlinear equation or an equation that corresponds to a graph.Solve equations by factoring or using other methods (for example, using the zeros of the graph to factor).Raising a value to a power, either using the ^ or the xy buttons.Work with decimals: change from decimal to fraction and vice versa.Be able to do basic calculations (+, -, *, /).
