Your "<span>h (x)=x 2 squared +6x-3" is ambiguous. If you meant "x squared," then you need only write x^2 OR "x squared," but NOT "x 2 squared."
I will assume that by "</span><span>h (x)=x 2 squared +6x-3" you actually meant:
</span><span>h(x)=x^2 +6x-3. To find h(3), subst. 3 for x: h(3) = (3)^2 + 6(3) - 3, or
h(3) = 9 + 18 - 3, or h(3) = 24.</span>
Answer:
Part A


Part B
Geometric Sequence
Part C
1/4,3/4,5/4,7/4,9/4

Part D:

Step-by-step explanation:
By definition, an Arithmetic Sequence holds the same difference between each following number.
Part A

<u>Explicit Formula</u>
To write an explicit formula is to write it as function.

<u>Recursive Formula</u>
To write it as recursive formula, is to write it as recurrence given to some restrictions:

Part B

Geometric Sequence, since 2*2=4 8*2=16 and 16*2=32 and 8+2=10 8+16=24
Part C

Arithmetic Sequence, difference

<u>Explicit Formula:</u>

<u>Recursive Formula</u>

Part D
(1.1,1.5,1.9,2.3,2.7) Arithmetic Sequence, difference d=0.4
<u>Explicit formula</u>

<u>Recursive Formula</u>

By doing base times area that is what I will do
I would say go with with B
