All you have to do is to substitute the given values of the function, for x in the equation.
f%28x%29+=+-x%5E3+-+3x%5E2+%2B+3x+%2B+7 Find f(-1) by substituting -1 for x.
f%28-1%29+=+-%28-1%29%5E3+-+3%28-1%29%5E2+%2B+3%28-1%29+%2B+7
f%28-1%29+=+1+-+3+-3+%2B7
f%28-1%29+=+1+-6+%2B+7
f%28-1%29+=+2
f%280%29+=+-%280%29%5E3+-+3%280%29%5E2+%2B+3%280%29+%2B+7
f%280%29+=+-+0+-+0+%2B+0+%2B+7
f%280%29+=+7
f%282%29+=+-%282%29%5E3+-+3%282%29%5E2+%2B+3%282%29+%2B+7
f%282%29+=+-8+-12+%2B+6+%2B+7
f%282%29+=+-20+%2B13
f%282%29+=+-7
