I need help with these 2 problems please and please make it legible.

Define f(0,0) in a way that extends f to be continuous at the origin. f(x,y) = In 19x2 -xy2 + 19y x2 + yz Let f(0,0) be defined to be (Type an exact answer.)Find parametric equations for the line tangent to the curve of intersection of the surfaces at the given point. Surfaces: x2+2y+22=10 y=2 Point: [1,2,2] 2 C Find the equations for the tangent line. Let z = g + 2t. x = D (Type an expression using t as the variable.) y = E (Type an expression using t as the variable.) 2 = E (Type an expression using t as the variable.)
