Q. What is the value of A when we rewrite 1.44−1.2x as Ax ?Choose 1 answer:(A) A=12144(B) A=1.44−1.2(C) A=1.441.2(D) A=1224x
Understand the problem: Understand the problem.We need to express the function 1.44−1.2x in the form of Ax, where A is a constant.
Rewrite function: Rewrite the given function in the required form.We have 1.44(−1.2x) and we want it to be in the form A(x). To find A, we need to isolate the base of the exponent such that the exponent is just x.
Identify base: Identify the base A.Since the exponent in the given function is −1.2x, we can equate A to 1.44 raised to the power of −1.2 to get the base in terms of x.A=1.44−1.2
Match choices: Match the expression for A with the given choices.Looking at the choices provided, we see that choice (B) A=1.44−1.2 matches our expression for A.
