Here are the solutions to the limit problems:

d) Evaluate limx2(6x2)\lim_{x \to 2} (6x-2)

Step 1: Substitute the value x=2x=2 into the function. Since 6x26x-2 is a polynomial function, we can find the limit by direct substitution. 6(2)26(2) - 2 Step 2: Perform the multiplication. 12212 - 2 Step 3: Perform the subtraction. 1010 The limit is 10\boxed{10}.

e) Evaluate limx2(2x2+x)\lim_{x \to -2} (2x^2+x)

Step 1: Substitute the value x=2x=-2 into the function. Since 2x2+x2x^2+x is a polynomial function, we can find the limit by direct substitution. 2(2)2+(2)2(-2)^2 + (-2) Step 2: Evaluate the exponent. 2(4)+(2)2(4) + (-2) Step 3: Perform the multiplication. 828 - 2 Step 4: Perform the subtraction. 66 The limit is 6\boxed{6}.
