Explanation:

y = x3 + x2 + 5                                     … (i)

y = x2 + x + 5                                      … (ii)

Solving (i) and (ii), we get,

x3 + x2 + 5 = x2 + x + 5

x(x2 − 1) = 0

∴ x = 0, 1, −1

∴ All three solutions for (i) and (ii) lie between −2 and 2.

∴ The two curves intersect thrice in the given range.

Hence, option (d).
