Your friend graphs the function represented by the input-output table. Is your friend correct? Explain your reasoning.

Incorrect.

Step-by-step explanation:

My friend is incorrect because the input values was plotted along the y-axis while the output values were plotted along the x-axis, which makes the graph totally incorrect.

The right way to plot the graph is to plot the input-values on the x-axis, while the corresponding output values should be plotted on the y-axis.

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
