Axis of symmetry of f(x)=(x+3)^2-8

Anna007 [38]

<u>ANSWER</u>

$x = - 3$

<u>EXPLANATION</u>

When a quadratic equation is in the vertex form,

$f(x) = a {(x - h)}^{2} + k$

the equation of axis of symmetry is simply

$x = h$

The given quadratic equation is

$f(x) = {(x + 3)}^{2} - 8$

We can rewrite this as

$f(x) = {(x - - 3)}^{2} - 8$

We now compare to

$f(x) = a {(x - h)}^{2} + k$

We have

$h = - 3 \: \: \: and \: \: k = - 8$

Therefore equation of axis of symmetry is:

$x = - 3$

Please i need helpp ion get math at all

fiasKO [112]

Answer:

you have to use the Pythagorean theorem. a^2 + b^2= c^2

72^2 + b^2 = 75^2

5184 + b^2 = 5625 (subtract 5184 from both sides)

b^2= 441 (find the square root of each side)

b= 21
