cho ham so y=f(x)=-2x+3 .Tinh f(-2);f(-1);f(0);f(-1/2);f(1/2)
Cho ham so y=f(x) xac dinh voi moi x E R thoa man tinh chat: f(a+b)= f(ab) voi moi a,b E R va f(-3). Tinh f(2014)
Please for kt Toan hoc ky 1
cho hai ham so y = f(x) = 2x - \(^{x^2}\) ; y = g(x) = x - 7 + 3 . tinh f(1) va g(2)
cho ham so : y=f(x)=1/2x
a,tinh f(-1),f(3),f(6)
b,ve do thi ham so da cho
cho ham so y=f(x)=ax.biet f(-3)=2
a, tinh he so a va ve do thi ham so
b, tim x de f(x)=-6,ungvoi gia tri a tim duoc o cau a
cho ham so y=f(x) tinh f(4) bet f(x)=(x-1).f(x-1) va f(1)=1
Cho ham so: y=f(x)=x^2-2/3*x+1
Tinh f(1) ; f(-1) ; f(0) ; f(-3) ; f(5)
Giup minh voi.Dang can gap
Cho ham so
f(x)=4^x/4^x+2
Tinh A=f(0)+f(1/101)+f(2/101)+f(3/101)+...+f(100/101)+f(1)
Cho ham so y = F(x) = 3x-1
a)Tinh f(0),f(-1)
b)Tinh gia tri tuong ung cua x voi y =2,-4
