Answer:

Bottom left graph.

Step-by-step explanation:

I answered this by finding the y-int.

8(0) - 3y = 18

-3y = 18

y = -6

And it has a positive relationship so the line slants from bottom left to top right.

Find the range of the function F(x) = (x-2)2 +2

viktelen [127]

(x - 2)^2 will always be positive and will have a minimum value of 0

so f(x) will have minimum of 2

Range is [2,∞)

Answer:

$(f\circ g)(4)=31$

Step-by-step explanation:

Composite Function

Given f(x) and g(x) real functions, the composite function named fog(x) is defined as:

$(f\circ g)(x)=f(g(x))$

For practical purposes, it can be found by substituting g into f.

We have:

$f(x)=3x+1$

$g(x)=x^2-6$

Computing the composite function:

$(f\circ g)(x)=f(g(x))=3(x^2-6)+1$

Operating:

$(f\circ g)(x)=3x^2-18+1$

Operating:

$(f\circ g)(x)=3x^2-17$

Now evaluate for x=4

$(f\circ g)(4)=3(4)^2-17=48-17$

$\boxed{(f\circ g)(4)=31}$

AB is tangent to O. If AO = 32 and BC = 98, what is AB? my guess is 130? please help!

Juli2301 [7.4K]

CO = AO = 32 (Are rays.)
BO = BC + CO = 98 + 32 = 130
AB ⊥ BO
⇒ ΔAOB is a rectangular triangle.
We use Pitagora's theorem.

$\displaystyle\\
AB = \sqrt{BO^2 - AO^2} = \sqrt{130^2 -32^2}=\\\\
= \sqrt{16900 -1024}= \sqrt{15876}= \boxed{126 }$
