Basic curves: exponential and logarithm
y = eˣ
Y₁ = e^(X)
Y= → 2nd → LN → X,T,θ,n → GRAPH
Explore an inputx = 0
Domain: All real inputs.
Increasing; y-intercept 1 and left-end asymptote y = 0.
y = e⁻ˣ
Y₁ = e^(−X)
Y= → 2nd → LN → (−) → X,T,θ,n → GRAPH
Explore an inputx = 0
Domain: All real inputs.
Use the negation key (−); decreasing, with y-intercept 1.
y = ln x
Y₁ = ln(X)
Y= → LN → X,T,θ,n → GRAPH
Explore an inputx = 1
Domain: x > 0.
Real inputs x > 0; x-intercept 1; vertical asymptote x = 0.
