Can you tell me which questions i used derivatives in and can you switch the derivatives to the secant method in the instantaneous rate of change

1. yo2x $7 x + 2x - 3 over the intervals [3.$4 Therefore, In the span of 1-3 seconds- the average rate of change b 4 m's Rate of charge: Pix)-lib)-fial b-8 b. duty =-2t +8 13.51 - given 0121' - -212)+8 - 4 Pyx) = [1(5) - 13145-3) The instantaneous rate of change at two seconds equals four. (12 x 5 '+7 x5 +2 -3)-(2x3 +7 x 3 *+2X3-301/2 5. = (1250 + 175 + 10 - 3)-(54+63+6-301/2 a. Lim x-1(3x*3+7x-16) 432 - 120 /2 - 3x 242 + 712-16 312/2 : 22 -156 b. 22 is the unning value of the function 3x*3 + 7x-16 at x=2 as well, when x gets closer to 2. fix) -2x 43x#1 2, 3x2+7x-16 gets closer to 22 Prime ()=4x143-7 a. Im ( 10x 3 -40) -164-4 -00 - indeterminate b. Lim x 9 8x -5x +17/6x +2x x 2030 47041 417 Q. Between 2.a and 2.b, both use the same process which is *(x) = 2x *+2x +1{ prior Died:" Both resulted in answers of seven as well. 3. The visual differences of a tangent line vs. a tangent line is that the secant line has two main SEOUL.1-L.L . indeterminate connections to the curved line whereas the tangent line will only connect with the curved line at a mid point instead of the two ends such as the secant line. 1/14 a. Lim 18141 1410-L. 2.1.L. Indeterminate a. /werage rate of change of the ball between one and free seconds; -20'2+4 xh . 2h -2 4x 43h
