Question 1 The graphs, y = f (x) , where f (z) = I Sx2 +1 if = = 1 andy = g(x), where g(z) = 2x are as follows. lz+3 if a>1 1 point Figure 1. The graph y = f(I) Figure 2. The graph y = g(I) Find the value of a). f(-1) = Number b). f (3) = Number c). f(g(0.5)) = Number 1). lim f(g(z)) = Number 1-+0.5 e). lim f(g(z)) = Number I +0.5 Question 2 Determine the following limit 25 - 93 lim 1 point 1-19 VI - 3 if it exists. Enter 'NA' (without the quotation marks) if limit does not exist. Answer : Question 3 Determine the following limit I + 21 - 2VI 1 point lim I-+7 V3x +7 - V14 + 2x if it exists. Enter 'NA' (without the quotation marks) if limit does not exist
