Is a square a one-to-one correspondence? (H) Sketch a graph of the function
Using your graph, determine if this function provides a one-to-one correspondence between the real numbers on the x-axis and the real numb ers on the y-axis. If it does give a one-to-one correspondence between the numbers on the two axes, justify your answer using your graph. If not, use your graph to explain why that function is not a one-to-one correspondence. In particular, does every number on the x-axis correspond to exactly one number on the y-axis? Does every number on the y-axis correspond to exactly one number on the x-axis?

- The circumference C of a circle is a function of its radius given by C(r)=2r. Express the radius of a circle as a function of its circumference. Call this function r(C) , Find r(36) and interpret its meaning,arrow_forwardUse the graph of the function f to find (a) the domain of f, (b) the function values f(0) and f(3) and (c) the range of f.arrow_forwardThe path of a ball is modeled by the function f(x)=120x2+3x+5, where fx is the height (in feet) of the ball and x is the horizontal distance (in feet) from where the ball was thrown. (a) What is the maximum height of the ball? (b) Which number determines the height at which the ball was thrown? Does changing this value change the coordinates of the maximum height of the ball?
