Find the slopes of the lines tangents to the graph of f at X=0,2, and 4 Graph f and sketch in the tangent lines at X=0,2 and 4

f(x)=x^2-4 ​

The table represents a linear function. what is the slope of the function? –6 –4 4 6

A. 127 cm^2 b. 144.5 cm^2 c. 172 cm^2 d. 50 cm^2

The brain volumes (cm cubed) of 50 brains vary from a low of 904 cm cubed to a high of 1488 cm cubed. use the range rule of thumb to estimate the standard deviation s and compare the result to the exact standard deviation of 175.5 cm cubed, assuming the estimate is accurate if it is within 15 cm cubed
