Answer:
x = -2
x = -10
Step-by-step explanation:
<u>Step 1 :</u><u> Rearrange</u>
x² + 12x + 20 = 0
<u>Step 2:</u><u> Factorise</u>
(x + 2)(x + 10)
<u>Step 3:</u><u> Find the roots / values of x</u>
Make each bracket equal zero.
(x + 2) = x = -2
(x + 10) = x = -10
Hope this helps!
Answer:
The growth factor of f(x) is less than the growth factor of g(x) (Option B)
Step-by-step explanation:
The growth factor of a function h(x)=a(b)^x is b.
1) f(x)=5(3)^x
The growth factor of f(x) is 3.
2) g(x)=a(b)^x
when x=0, g(0)=1→a(b)^0=1→a(1)=1→a=1
g(x)=1(b)^x→g(x)=(b)^x
when x=1, g(1)=5→(b)^1=5→b=5
g(x)=(5)^x
The growth factor of g(x) is 5.
The growth factor of f(x)=3 is less than the growth factor of g(x)=5
You simplify the fraction by dividing 2 to the nominator and the denominator. So 24/2=12, 8/2=4, 6/2=3. You can only divide a root with a root number so in this case the root three doesn't get affected
