Find the vertex, x-intercepts, y-intercept and sketch the function.

Decide whether the relation defines a function.

Decide whether the relation defines a function.
{( -3,  3), ( -1,  -1), ( 3,  -5), (13,  2)}

Solution:

We check that every element in the domain (the set of all first coordinates) corresponds to only one element of the range (the set of all second coordinates). For this relation the answer is yes, so this relation is a function

7 raised to 5x-8 and 5 raised to x+2 if product of these two is equal to 30625 then how to find value of x

:)

Solve: x= 3 + sqrt(3x -5)

.

Solve: sqrt( 3x+3 + sqrt(x+2)) = 5

.

Radicals/918343: 3 = x-2√x

divide by a polynomial: (x^4+2x^3-6x^2-7x-41)/(x^2+x-10)

Find all zeros of the polynomial: P(x)=(x^2+4)(x^2+x)-(x^2+4)
