Answer:

2x² + \frac{3}{2} x - 5

(f + g)(x) = f(x) + g(x), thus

f(x) + g(x)

= \frac{x}{2} - 2 + 2x² + x - 3 ← collect like terms

Choose the correct graph of the function y=-1/2√x+3+2
Bad White [126]

Find y intercept

\\ \rm\rightarrowtail y=-\dfrac{1}{2}\sqrt{x+3}+2

\\ \rm\rightarrowtail y=-\dfrac{1}{2}\sqrt{0+3}+2

\\ \rm\rightarrowtail y=\dfrac{-\sqrt{3}}{2}+2

\\ \rm\rightarrowtail y=\dfrac{4-\sqrt{3}}{2}

\\ \rm\rightarrowtail y=\dfrac{4-1.732}{2}

\\ \rm\rightarrowtail y=\dfrac{2.368}{2}

\\ \rm\rightarrowtail y=1.184

  • y intercept=(0,1.2)

Select the option fo “?” That continues the pattern in each question. <br> 3, -6, 12, 4, 20, ?
Elza [17]

Answer:

The sixth number in series is 13.

Step-by-step explanation:

Given series : 3, -6, 12, 4, 20, ?

The pattern followed by the series is:

The first number = 3

Second number = 3 - 9 = - 6

Third number = - 6 + (9 ×2) = -6 + 18 = 12

Fourth number = 12  - 8 = 4

Fifth number = 4 + (8 ×2) = 20

Sixth number = 20 - 7 = 13

Seventh number = 13 + (7 ×2) =  13 + 14 = 27 and so on.

So as per the above pattern, the sixth number in the series is 13.
