Which functions have an axis of symmetry of x = –2? Check all that apply.

ELEN [110]

Answer : $Answer :f(x) = x^2 + 4x + 3 \ and \ f(x) = -2x^2 - 8x + 1$

Given: axis of symmetry of x = –2

To find axis of symmetry we use formula $x =\frac{-b}{2a}$

We check which equation has axis of symmetry x= -2

(1) $f(x) = x^2 + 4x + 3$

a=1 , b=4 so axis of symmetry $x =\frac{-4}{2*1} = -2$

(2) $f(x) = x^2 - 4x - 5$

a=1 , b=-4 so axis of symmetry $x =\frac{-(-4)}{2*1} = 2$

(3) $f(x) = x^2 + 6x + 2$

a=1 , b=6 so axis of symmetry $x =\frac{-6}{2*1} = -3$

(4) $f(x) = -2x^2 - 8x + 1$

a=-2 , b=-8 so axis of symmetry $x =\frac{-(-8)}{2*(-2)} = -2$

(5) $f(x) = -2x^2 + 8x - 2$

a=-2 , b=8 so axis of symmetry $x =\frac{-(8)}{2*(-2)} = 2$

So $f(x) = x^2 + 4x + 3$ and $f(x) = -2x^2 - 8x + 1$ has axis of symmetry x=-2

Solve by substitution<br> x = y - 3<br> 2x + y = 12<br><br> Help!!

Karo-lina-s [1.5K]

Let's plug in what x =, y-3 into 2x+y=12
2 (y-3)+y=12
distribute 2 to both y and -3
2y-6+y=12
add all ys
3y-6=12
+6 both sides
3y=18
÷3 both sides

y=6

plug in y into x=y-3 to find x
x=6-3
x=3

Identify each sequence as arithmetic or geometric. Explain your answer, and write an explicit formula for the

hammer [34]

Answer:

Arithmetic sequence

$a_n=\frac{1}{2}-n$ for $n\geq 1$

Step-by-step explanation:

We are given that a sequence

$-\frac{1}{2},-\frac{3}{2},-\frac{5}{2},-\frac{7}{2},...$

We have to identify the sequence as arithmetic or geometric and write an explicit formula .

$a_1=-\frac{1}{2}$

$a_2=-\frac{3}{2}$

$a_3=-\frac{5}{2}$

$a_4=-\frac{7}{2}$

$d_1=a_2-a_1=\frac{-3}{2}+\frac{1}{2}=-1$

$d_2=a_3-a_2=-\frac{5}{2}+\frac{3}{2}=-1$

$d_1=d_2=-1$

When the difference of consecutive terms is constant then the sequence is an arithmetic.

Hence, the sequence is an arithmetic.

$a_n=a+(n-1)d$

$a_n=-\frac{1}{2}+(n-1)(-1)=-\frac{1}{2}-n+1=\frac{1}{2}-n$ for $n\geq 1$
