Graph the square root of the following function. State the domain and range of the square root of the function.

y = -2x + 4

why are the domain and range of square root function restricted
to [0,∞) ?

determine the range and domain of the following: the function k
defined by k(x)= square root x-3

Find the domain of the function g(x) = square root of 3x+3

Estimate the area A between the graph of the function f(x)=
square root of x and the interval [0,49]. Use an approximation
scheme with n=2,5, and 10 rectangles. Use the right
endpoints.
Round your answers to three decimal places.

axis symmetry, graph max or min value, domain, range and all
intervals where function increases or decreases. f(x)=5(x-3)^2+6
f(x)=-7(x-8)^2+1 f(x)=-6(x+4)^-8 f(x)=2(x+2)^2+9

What is the domain and range of
y=1/2x²+4?

DO NOT DO THE GRAPH OR THE DOMAIN OR RANGE PART. THOSE DO NOT
COUNT. WE ARE NOT DOING THEM IN MATH 1003.Find the factors that are
common in the numerator and the denominator. Then find the
intercepts and asymptotes. (If an answer does not exist, enter DNE.
Enter your asymptotes as a comma-separated list of equations if
necessary.)

Let f be a function with domain the reals and range the reals.
Assume that f has a local minimum at each point x in its domain.
(This means that, for each x ∈ R, there is an E = Ex > 0 such
that, whenever | x−t |< E then f(x) ≤ f(t).) Do not assume that
f is differentiable, or continuous, or anything nice like that.
Prove that the image of f is countable. (Hint: When I solved...

• The range of f is the domain of g and the
domain of f is the range of g.
•
f(a) = b if and only if g(b) = a.
•
(a, b) is on the graph of f if and only if (b, a) is on
the graph of g.
The function
f(x) = x3 + 7x + 5
is one-to-one. Since finding a formula for its inverse is beyond
the scope of this textbook, use Properties of...
