Answer:
They have the same x-value
f(x) has the greater minimum
Step-by-step explanation:
To find the vertex of a second degree equation, in this case the minimum value, we can use the following equation:
x = -b / 2a
Remember that a second degree equation has the following form:
ax^2 + bx + c
so a = 1, b = -8 and c = 7. Now you have to substitute in the previous equation
x = - (-8) / 2(1)
x = 8 / 2
x = 4
This means that the two functions have the same x-value.
The y value of f(x) would be
f(4) = (4)^2 - 8(4) + 7
f(4) = 16 - 32 + 7
f(4) = -9
So the vertex, or minimun value of f(x) would be at the point (4, -9).
The vertex, or minimun value of g(x) is at the point (4, -4).
So f(x) has a minimum value of -9 and g(x) a minimum value of -4.
It will just be a+b-180 because there are no like terms to put together :)
Answer:
These are the steps to do it since there is no equations provided
Step-by-step explanation:
1.) First, replace f(x) with y . ...
2.) Replace every x with a y and replace every y with an x .
3.)Solve the equation from Step 2 for y . ...
4.) Replace y with f−1(x) f − 1 ( x ) .
