The table shows the number of students graduating from a high school in selected years. Use a calculator to write a quartic model for the number of graduates in a given year since 1980. Then use the model to estimate the number of graduates in 1992. Year 1981 1984 1985 1986 1989 1990 Number of 210 252 261 272 Graduates 321 340 P(x) 0.14x³+ 1.95x2-20.17x- 191.86 The estimated the number of graduates in 1992 is 399. P(x) = -0.04x4 +1.06x³-8.99x2 + 40.05x + 177.92 The estimated the number of graduates in 1992 is 367. P(x) = 0.04x4 - 1.06x3 + 8.99x2 - 40.05x - 177.92 The estimated the number of graduates in 1992 is 367. P(x) = 0.14x³ -1.95x² + 20.17x + 191.86 The estimated the number of graduates in 1992 is 367.

The table shows the number of students graduating from a high school in selected years. Use a calculator
to write a quartic model for the number of graduates in a given year since 1980. Then use the model to
estimate the number of graduates in 1992.
Year
1981
1984 1985 1986 1989
1990
Number of
Graduates

340
P(x) = 0.14x³+ 1.95x2 -20.17x- 191.86
The estimated the number of graduates in 1992 is 399.
P(x) = -0.04x4 + 1.06x3 - 8.99x² + 40.05x + 177.92
The estimated the number of graduates in 1992 is 367.
P(x) = 0.04x4 - 1.06x³ + 8.99x2 - 40.05x - 177.92
The estimated the number of graduates in 1992 is 367.
P(x) = 0.14x³1.95x² + 20.17x + 191.86
The estimated the number of graduates in 1992 is 367.
