Step-by-step explanation:
problem 13:
12g+24, 3(4g+8)
problem 14
9a+6, 3(a+2)+6a
6(a+1)+3a
Answer:
steps below
Step-by-step explanation:
f(x) = 4√x - 2x ... x≥0
f'(x) = 2/√x - 2
critical points: x=0, x=1
x=1 y = 4√1 -2x1 = 2
extreme: (<u>1</u>,2) tangent line parallel to x axis: y = 2 .... <u>x = 1</u>
x = 0 (x≥0): (0,0) tangent line parallel to y axis: <u>x = 0</u>
