how can I solve these problems using MatLab? 1.Use the plot command to plot the function f ( x ) = x 2 − 10 √ x + 2 for 0 ≤ x ≤ 5 . 2.Use the plot command to plot the function f ( x ) = ( 0.5 x 4 + 1.1 x 3 − 0.9 x 2 ) e − 0.7 x for − 3 ≤ x ≤ 10 .

在 MATLAB Online 中打开

syms x %requires symbolic toolbox
f  = 2 * x - 10 * sqrt ( x ) + 2
figure
fplot(f,[0 5])
f1 = ( 0.5 * x * 4 + 1.1 * x * 3 - 0.9 * x * 2 ) * exp(1) - 0.7 * x
figure
fplot(f1,[-3 10])
%alternatively, you can use fplot, which is part of base MATLAB
f = @(x) x.^2 -10*sqrt(x) +2
fplot(f,[0 5])
