@douglaswinslowcooper This one I actually dont get at all. I know you have to find the tangent line and fill in the chart but thats about it
Sorry if it seems like im asking for alot but im studying for finals sooo yah
For the f(x) row just plug in square root of the x it asks and round it to four decimals. For the second row T(x) [sqrt(2) - f(x) you put in for the x] / [2 - x it asks]
ok so do the sqrt of x for the values at the top of the chart
f(x) = sqrt(x) The derivative, f'(x) = 1/(2sqrt(x)) at x = 2 the slope is 1/(2sqrt(2)) So, the equation of the tangent line is y = x/(2sqrt(2)) + b Plug in the values you were given(2,sqrt(2)) and you have, sqrt(2) = 2/(2sqrt(2)) + b sqrt(2) = 1/sqrt(2) + b b = sqrt(2) - 1/sqrt(2) So, the equation of the tangent line is y = 1/(2sqrt(2)) + sqrt(2)-1/sqrt(2)
Now you just need to evaluate that equation for each value of x that you need and fill in the chart
oops, for the tangent line I meant y =x/(2sqrt(2)) + sqrt(2)-1/sqrt(2)
thisis for the T(x) correct?
Yes
ok so for the f(x) I just take the sqrt of the number at the top
