What are the roots of y = x2 – 3x - 10?
0 -3 and -10
0-2 and 5
2 and -5
3 and 10

roots:   -2   and 5

Step-by-step explanation:

What are the roots of y = x2 – 3x - 10?

we see...

factor  -10    using the X-method.

-10 =  2 * -5

where  2 + -5 = -3

so

y = (x +2)(x - 5)

roots are  -2 and 5

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

the factor is 2

step-by-step explanation:

let f(x)=8(3^(x−2)+2)

to stretch a graph by 3, it would be 3f(x)

g(x) =3f(x)

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

x     −2     0     2     4     6

f(x) 1/64 1/16   1/4     1     4

1/64 * z * z = 1/16

i multiplies by z twice because it its 2 steps from -2 to 0

1/64 z^2 = 1/16

multiply by 64 to clear the fraction on the left side

1/4 * 64 z^2 =1/16 *64

z^2 = 4

take the square root of each side

sqrt(z^2) = ±sqrt(4)

z = ±2  

we are multiplying by 2 each time.
