I need just the graphs for this two questions please just graphs

Q3 The volume of water in a tank, Vm3, over a 10 month period is given by the function V(t) = 2t - - 16t + 40, where t is in months and t E [0, 10]. Use an appropriate standard engineering software such as MATLAB, CAS calculator, programmable calculator, Excel software, to find the volume of water in the tank after 10 months. Use an appropriate standard engineering software such as MATLAB, CAS calculator, programmable calculator, Excel software, to solve and analyse this problem mathematically, including graphing of the function required for this engineering application. PC 1.1, 1.2, 1.3, 2.1, 2.3, 2.4, 2.5 A: Exponential/Logarithmic Functions Q4 Use an appropriate standard engineering software or MATLAB to solve and determine g(x) by manipulating the mathematical values below: g ( x ) =-e";g (-2), 8 (v3),8 (3.6) Use an appropriate standard engineering software such as MATLAB, CAS calculator, programmable calculator, Excel software, to solve and analyse this problem mathematically, including graphing of given function
