f%28x%29+=+-+0.001718x%5E4+%2B+0.087326x%5E3+%96+1.3367x%5E2+%2B+12.46x+%2B+3.914 plug in x=2.5


f%28x%29+=+-0.067109375%2B1.36446875%968.354375%2B31.15%2B3.914
f%28x%29+=+1.29735937%968.354375%2B35.06400
f%28x%29+=+1.29735937%2B26.709625
f%28x%29+=+28.0069844
Then for the next one do the same thing, but instead of 2.5 plug in 12
