evaluate the linit. please explain steps

5. Evaluate the limit. It is possible that the limit may not cxist. limx8x8x8 6. Evaluate the limit by using algebra followed by direct substitution. Suppose f(x)=x+8limh0(hf(6+h)f(6)) 7. Evaluate the limit (hint: use squecze theorem). limx0cos(5x)xcsc(3x) 8. Evaluate the limit. limh11h1m+7h= 9. Use squecze theorem to evaluate the following limit. limxxsinx 10. Evaluate the following infinite limits. (Your answer for both parts will be either ). limx(27),92x34x limx(M)02x34x 11. Evaluate the following limit at infinity (hint: multiply by the conjugate). limx(x24x+1x)= 12. Let f(x)=2+x4. (a) Find f(x). f(x)= (D) Find the slope of the tangent line at x=2. slope f(2)
