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
B. your answer is an angle
Answer:
Step-by-step explanation:
in y = mx + b form, the slope is in the m position and the y intercept is in the b position.
y = mx + b
slope(m) = 5/7
y int (b) = -3
y = 5/7x - 3 <===
K×x+8=4
k×x=4-8
k×x=-4
x=-4/k
