what is linear equation with one unknown 2x+5=3
I was wrong. I didn't move all constants to the right of the equation.

X int
Y int of
f(x) =x²+4x+4/x+2
f(x) =x³1/x1
can I get help with this?

Are they two separate problems or are the two functions a system?

if theta =30degree so COS2 theta = 1 10 square theta upon 1 + tan squared theta
how to compute this
1. g(1x)
2. f(x2)
3. g (x/5)
4. f (x) g (x)
not much
For functions, there are two conditions for a function to be the inverse function:
1 g(f(x)) = x for all x in the domain of f
2f(g(x)) = x for all x in the domain of g Notice in both cases you will get back to the element that you started with, namely, x.

Prove that
4sin503tan 50=1
False statement so you cannot prove it
Wilson
f(x)= 1 x f(x)=1x is shifted down 4 units and to the right 3 units.
f (x) = −3x + 5 and g (x) = x − 5 /−3

I want to know partial fraction Decomposition.
classes of function in mathematics
wish i knew calculus to understand what's going on 🙂
@dashawn ... in simple terms, a derivative is the tangent line of the function. which gives the rate of change at that instant. to calculate. given f(x)==ax^n. then f'(x)=n*ax^n1 . hope that help.
Christopher
maybe when i start calculus in a few months i won't be that lost 😎
