is there a way of specifically looking up a course by number. I.E. math 1.2.3 quiz? having hard time searching for f(x)=x². What is g(x)? without being to upload the graph?thanks

Well, the curriculum my school uses if Big Ideas Math, used widely across many schools, so it is easy to look up answers and stuff. Yes, it is possible, follow steps below, this may help.

Step-by-step explanation:

Go to quizlet

Click "explanations for textbook"

Search for your textbook/course

Select your textbook/course

Go to specific section and specific problem number

It gives a step by step explanation which is really helpful

answer: the answer is (d)

step-by-step explanation:   we are given four functions and we are to select which one represent exponential decay.

the functions represents straight lines, and so there is no exponential growth or decay. these two functions are graphed in the attached figure.

the function both are exponential functions, where the first one shows exponential decay because as the value of x increases, the value of y is decreasing and the second shows exponential growth, because x and y increases or decreases simultaneously. see the attached figure.

thus, the correct option is (d)
