<h3>This curve passes the vertical line test, therefore it is a function.</h3>

<h3>The idea behind the vertical line test is that if you draw any vertical line, it has to intersect the curve only once. If there is more than 1 intersection, then it is not a function.</h3>

ps: This is a quadratic function of equation

$f(x) = - x {}^{2} + 4$

What is 10 of 25%......................................

tia_tia [17]

the math behind it:
your equation looks like this: .25x = 10
then you divide both sides by .25 and then ur equation looks like this: x=40
by the way the variable x stands for the number you are looking for. and since x=40, the number you are looking for is 40
well i hope i helped!

Suppose it is known that for a given differentiable function y=f(x), its tangent line (local linearization) at the point where a

Answer:

y(-4) = 5

y'(-4) = -7

Step-by-step explanation:

Hi!

Since the tangent line T and the curve y must coincide at x=-4

y(-4) = T(-4) = 5

On the other hand, the derivative of the curve evaluated at -4 y'(x=-4) must be the slope of the tangent line. Which inspecting the tangent line T(x) is -7

That is:

y'(-4) = -7
