Answer:
3
Step-by-step explanation:
t-4t^2+2t^3
Rewriting this in order from largest to smallest exponent
2t^3 -4t^2 +t
The highest power is 3
So this is degree 3
We get the value of h and k as 9 and -8
The quadratic function g(x) = a(x - h)^2 + k, if a is not equal to 0,which means that equation has a quadratic value then it is said to be in standard quadratic form.
If a is positive, then the graph opens upwards,
If a is negative, then it opens downwards.
The line of symmetry of the quadratic equation is the vertical line x = h, and the co-ordinate of the point of vertex is (h,k).
We are given the co-ordinate of the vertex point in the question and hence all that is required is to equate it.
Therefore, the values of h and k are 9 and -8 in the given equation in vertex form

Answer:
f(x)=1 (B)
Step-by-step explanation:
f(x) = 2X-7
f(4) = 2(4)-7
=8-7
=1
25 is 5 more than 20 which is 25% more since 5/20 = 1/4 = 25%
To check (1.25 * 20 = 25)
