(a) Given the function f(x) = e"+2 – 2 i. Give the equation for the graph shifted 2 units to the left, 2 units downward and reflected about y-axis. ii. Show that the function f(x) obtained in (i) is one-to-one. Determine the inverse of the new function from (i). iii. State the domain and range of the inverse function obtained in (ii). (b) Using Intermediate Value Theorem, justify that the equation a4 – 2a² + } = 0 has two solutions in the interval [-1, 1].

Rate of Change
The relation between two quantities which displays how much greater one quantity is than another is called ratio.
Slope
The change in the vertical distances is known as the rise and the change in the horizontal distances is known as the run. So, the rise divided by run is nothing but a slope value. It is calculated with simple algebraic equations as:
