function f=fun_es(x); f=0.5*exp^(x./3)-x.*x.*sin(x); end编写一个函数M文件fun_es(x),计算如下函数其中的变量可以为标量,也可以为向量（数组）在MATLAB里输入如下指令检验此函数 fun_es(3) fun_es([1 2 3 4])请问 Input argument x is undefined.function y=f(x) y=exp(-x)+exp(x); 请问几道分段函数的问题function:f(X)={3x-7,if x find the inverse of the function:f(x)= (4x-1)/(2x+3) A function f is such that f(x)=ln(5x-10) solve f(x)=0 several values of the function f are shown. the function g is defined by g(x)=f(3x+1).what is the value of g(2) If f(x)=log(x).write out the domain and range of the function. What are the Domain and Range of the function f(x)=-2log(x)-4? SAT数学题 Function f is defined by f(x)=(x-a)(x-b)/(x-c),where 0 matlab我这两行定义有什么错吗.function f=fun(x) f=1/(1+x^2); 关于一题SAT数学题If f(x)=x^3+1 and of f^(-1)（x) is the inverse function of f,what is f^(-1)(4)? 答案是1.44 求详细解答! 谢谢谢!inverse function 是什么? MATLAB中function f=fun（x,y）,“f=”代表什么意义啊?我看到很多MATLAB中函数定义为function f=fun（x,y）型,其中“f=”代表什么意义啊? 菜鸟求教：MATLAB limit用法>> f=sym('x^2+4*x+10')>> limit(f,x,a)Undefined function or variable 'x'.>> limit(f,a)Undefined function or variable 'a'.还有：>> f=sym('sqrt(1+1/n)');>> limit(f,n,inf)Undefined function or variable 'n'.>> int(f,v)U what is the value of the discriminant for the function f(x)=8x^2+13x+7? if f(x) is a linear function such that f(2)=5 and f(4)=13,f(x)=? Let f be the function with derivative given by f'(x)=sin(x*x+1).How many relative extrama dose f have on the interval 2 matlab中如何用function建立一个y=f(x)函数?直接function y=f(x) y=x.^2+3*x+2不对啊,直接function y=f(x)y=x.^2+3*x+2;factor(p)运行不了 Find a formula for the inverse of the function f(x) = ln (2 x+9).3Q
