Use the parabola tool to graph the quadratic function. f(x)=(x-2)^2-3 graph the parabola by first plotting its vertex and then plotting a second point on the parabola

Step-by-step explanation:

Simply by comparing the given

f(x)=(x-2)^2-3   to

f(x) = (x-h)^2 + k, we see that h = 2 and k = -3, which tells us that the vertex of the graph is (2, -3).  This parabola opens up because the coefficient of (x-2)^2 is +1.

Evaluating f(x)=(x-2)^2-3 at x = 4 (an arbitrary value), we see that

                 f(4) = (4-2)^2 - 3 = 4 - 3 = 1.

The point (4, 1) is also on the graph of this parabola.

Graph the vertex (2, -3) and the arbitrarily chosen point (4, 1).  Remember that (2, -3) is the minimum of this function, so for x other than 2, the y-value is greater than -3.

step-by-step explanation:

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
