Answer:
a) -4 mult. 2
b)
c) 2, quadratic
Step-by-Step Explanation:
A polynomial graph has several features we look for to determine the equations.
- The zeros of the function are the x-intercepts. If the x-intercepts touch but do not cross then the intercepts have an even multiplicity like 2, 4, 6, etc. If the x-intercepts cross over then they have an odd multiplicity.
- Degree is the exponent or multiplicity of each zero. Therefore if we know the multiplicity of each zero we can add them together to find or make an educated guess for the degree of the entire polynomial.
- The shape of the graph tells us what type of polynomial. Odd degrees have a backwards S shape. Even degrees have a W shape. The shape can even tell us the if the equation has a positive or negative leading coefficient. Upside down W or an M shape is negative. While a sideways S shape is negative.
In this graph, there is one real zero: -4
We can write them in intercept or factored form as (x+4) since x+4=0 gives x=-4.
Because the graph never crosses the x-axis it has an even multiplicity of at least 2.
The graph is facing up and is a U shape. This can only be a quadratic of degree 2. It is positive.
This means the function has a degree of 2.
So Jada for 1 day, gets charged $30 flat
now, she drove 2 days, so...she's charged 2 * 30 or 60 bucks
plus the mileage
is 0.5 per mile.... so... 1 mile is 0.5
2 miles 2 * 0.5
3 miles 3 * 0.5
4 miles 4 * 0.5
5 miles 5 * 0.5
x miles x * 0.5
she drove "x" miles, whatever that is
we also know, her total cost in the end, was 360
so... those 360 include the 2 days charge, 30 * 2
plus the mileage, x * 0.5 or 0.5x
so... one can say that
360 = (30 * 2) + 0.5x <---- solve for "x"
To nearest cm
So if I have 1.5 it rounds to 2
As if I have 1.4 it rounds to 1
Hope this helps if you still don’t get it comment
The answer is letter d. The Fibonacci Sequence states to add the 2 previous number to get the next number starting with 1. So, 1 + 0=1, 1+1=2, 1+2=3, 2+3=5,3+5=8, 5+8=13, etc....
I added 13+21 to get 34. Then add 21+34 to get 55. Then add 34+55 to get 89.
