What are the next 2 terms in the sequence -9,-8,-4, 5, 21, 46,

grin007 [14]

Answer:

-9,-8,-4, 5, 21, 46,95,159

Step-by-step explanation:

We keep adding the square numbers to the previous terms

$-9+1^2=-8$

$-8+2^2=-4$

$-4+3^2=5$

$5+4^2=21$

$21+6^2=46$

The next term is $46+7^2=95$

The next one is $95+8^2=159$

We got this by observing the pattern

Find the inverse of the following functions f(x)=6-3x g(x)=x+2

astraxan [27]

      f(x) = -3x + 6
    y = -3x + 6
      x = -3y + 6
   x - 6 = -3y
   -3    -3
⁻¹/₃x + 2 = y
⁻¹/₃x + 2 = f⁻¹(x)

g(x) = x + 2
   y = x + 2
   x = y + 2
x - 2 = y
x - 2 = g⁻¹(x)

Identify the vertex for the graph of y = 2x2 + 8x − 3. (2, 21) (2, 17) (−2, −11) (−2, −27)

Finger [1]

$\bf \textit{vertex of a vertical parabola, using coefficients}
\\\\
\begin{array}{lcccl}
y = & 2x^2& +8x& -3\\
&\uparrow &\uparrow &\uparrow \\
&a&b&c
\end{array}
\qquad 
\left(-\cfrac{ b}{2 a}\quad ,\quad c-\cfrac{ b^2}{4 a}\right)
\\\\\\
\left( -\cfrac{8}{2(2)}~~,~~-3-\cfrac{8^2}{4(2)} \right)\implies \left( \cfrac{-8}{4}~~,~~-3-\cfrac{64}{8} \right)
\\\\\\
\left(-2~~,~~-3-8 \right)\implies (-2~~,~~-11)$
