Answer:
The function f(x) is not given, I used a different function but the approach and steps is the same .
Step-by-step explanation:
- Given the function f(x) = 2x2 - 8x + 5
compare with the normal quadratic equation ; ax2 + bx + c = f(x)
- since a is greater than zero i.e a > o {positive}
As such, it has a minimum
hence for minimum value; x = -b/2a
x = -(-8)/2 x 2
x = 8/4 = 2
plugging the values of x in f(x) ; f(2) = 2(2)^2 -8(2) + 5
f(2) = -3, hence it has minimum value and the minimum value is -3
Checking the graph:- when x = 1 y = 0 so it cant be y = x^4
y = log4 x
is the same as
x = 4^y
Checking the graph, when x = 4, y = 1
Plugging these into the above 4 = 4^1 = 4
So the correct choice is first one
Answer:
The answer to the problem is C
Answer:
x = 15
Step-by-step explanation:
These angles are supplementary so you'd set up an equation like 3x -15 +150 = 180 then solve for x from there.
