Which function families have vertical symmetry?

1 answer:

8 0

The functions which are even are symmetric to y-axis. By even functions, it means that f(x) = f(x) for all the domain values. Thus even functions for example, x^2, 1+x^2, cosx, x^4 all follow the conditions i.e. f(x) = f(x) and thus they are symmterical to y-axis.

TIMED QUESTION Which are the roots of the quadratic function f(b) = b2 – 75? Select TWO options.

Setler [38]

Answer:

$b=5\sqrt{3}$ (b = 5 StartRoot 3 EndRoot)

and

$b=-5\sqrt{3}$ (b = Negative 5 StartRoot 3 EndRoot)

Step-by-step explanation:

we have

$f(b)=b^{2}-75$

we know that

The roots of the quadratic function are the values of x when the value of the function is equal to zero

For f(b)=0

$b^{2}-75=0$

Solve for b

Adds 75 both sides

$b^{2}=75$

take square root both sides

$b=(+/-)\sqrt{75}$

Simplify

$b=(+/-)5\sqrt{3}$

therefore

$b=5\sqrt{3}$ (b = 5 StartRoot 3 EndRoot)

and

$b=-5\sqrt{3}$ (b = Negative 5 StartRoot 3 EndRoot)

(y + 5)(y – 9) = 0<br> need help asap!!

OLEGan [10]

Set each equation equal to zero.

y + 5 = 0

Subtract 5 from both sides.
y = 0 - 5
y = - 5

y - 9 = 0

Add 9 to both sides
y = 0 + 9
y = 9

y = - 5, 9
