Question

find the tangent lin to the curve y=√x at x=4​

Answer 1

Explanation:

your answer is x to the power root 4

Answer 2

Answer:

given curve --- y=√x -------> y=x^½

therefore dy/dx = ½x^-½ = 1/2√x

for when x = 4, y = 2 (since y = √x)

y-2 = 1/4 (x-4)

= 4y-8 = x-4

= 4y = x+4

= y = (x+4)/4
