Whats the vertex of the graph y=-x^2

yawa3891 [41]

(0,0) you could use x=-b/2a but since your b term is nonexistant the whole term goes to 0 for the x value. Plug x=0 into the original equation which gives you another 0. ezpz

How do you determine if an equation is a function?

Svetradugi [14.3K]

Answer:

It is relatively easy to determine whether an equation is a function by solving for y. When you are given an equation and a specific value for x, there should only be one corresponding y-value for that x-value. For example, y = x + 1 is a function because y will always be one greater than x.

Calculus help needed!

mezya [45]

$f(x)=\ln x\\\\g(x)=\ln11x=\ln11+\ln x\ \ (\ln11=const.)\\\\h(x)=\ln x^2=2\ln x\\\\p(x)=\ln3x^2=\ln 3+\ln x^2=\ln3+2\ln x\ \ (\ln3=const.)$

Used:

$\ln a+\ln b=\ln(ab)\\\\\ln a^n=n\log a$

Functions have the same derivatives if they differ a constant.

h(x) = f(x); g(x) = f(x) + const.

h'(x) = f'(x)

g'(x) = (f(x) + const.)' = f'(x) + (const.)' = f'(x) + 0 = f'(x)

h'(x) = g'(x)

Therefore yuor answer is A. f'(x)=g'(x)

$f'(x)=(\ln x)'=\dfrac{1}{x}\\\\g'(x)=(\ln11x)=\dfrac{1}{11x}\cdot11=\dfrac{1}{x}$

Used:

$(\ln x)'=\dfrac{1}{x}\\\\f'(g(x))=f'(g(x))\cdot g'(x)$

Which rows represent when (p ∧ q) ∨ (p ∧ r) is true?\

tatyana61 [14]

<span>the statement is ambiguous, it must be written as (p ∧ q) ∨ r
or p ∧ (q ∨ r).</span>
