Describe the x-values at which f is differentiable. (Enter your answer using interval notation.) f(x) = x^2 − 4, x ≤ 0
4 − x^2, x > 0

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
