Answer

Simplify the expression by canceling out the common factor of h: f(x+h,y)f(x,y)h=16hy2h=16y2

Steps

Step 1 :Substitute f(x+h,y) into the numerator: f(x+h,y)=16(x+h)y2

Step 2 :Substitute f(x,y) into the numerator: f(x,y)=16xy2

Step 3 :Substitute the values into the expression: f(x+h,y)f(x,y)h=16(x+h)y216xy2h

Step 4 :Simplify the numerator: 16(x+h)y216xy2=16xy2+16hy216xy2=16hy2

Step 5 :Substitute the simplified numerator back into the expression: f(x+h,y)f(x,y)h=16hy2h

Step 6 :Simplify the expression by canceling out the common factor of h: f(x+h,y)f(x,y)h=16hy2h=16y2
