Idk what are your questions?
Numerator , denominator, mixed fractions, proper fractions
This is a parabola which looks like an inverted U. Its will have a maximum value when t = 7 as we see from the vertex form below:-
- t^2 + 14t - 40
= - ( t - 7)^2 + 49 - 40
= -(t - 7)^2 + 9
There is an axis of symmetry at x = 7.
so a is true since 7 is the maximum value of the function and its less at t = 6.
c is also true because of the symmetry about t = 7
Answer:
x = 1 and x = 9
Step-by-step explanation:
the known solutions are simply the values of x which causes the SAME number to show up in f(x) and g(x).
if we go down the table, we see that for x = 1, the same number 14 shows up for both f(x) and g(x), hence x=1 is a solution.
the same occurs for x = 9 giving 6 as the same solution for f(x) and g(x)
no other values of x causes this to occur.
hence the 2 known solutions are x = 1 and x = 9
