6.1 practice problems 6.1 practice problems 1. 2^12 or 4096 2. 3^2/ 4^2 = 9/16 3. -5^-2 or 1/25 4. x^0 =1 5. 70b^2 6.2 problems State whether or not the given function is a polynomial. If so, then state the degree, type, and leading coefficient. 1. f(x)= 12-5x YES, 1, linear 2. f(x)= x+ π NO 3. f(x)= -2x^3-3x^-3+x Yes, 3, cubic 4. f(x)= x^2-x+1 yes, 2, square 5. f(x)= 3x^3 Yes, 3, cubic When x=5, evaluate the given polynomial functions using direct substitution. 1. f(x)= 2x^3+5x^2+4x+8 f(x)= 403 2. f(x)=x+1/2x^3 3. f(x)=5x^4-8x^3+7x^2 4. f(x)=11x^3-6x^2+2 5. f(x)=7x^3+9x^2+3x

When x=-3, evaluate the following fuctions using synthetic division. 1.f(x)= 3x^5+5x^3+2x+9 2. f(x)=x^2+1/2x-3 3. f(x)=x^4-6x^2+7x 4. f(x)=4x^3+x^2+2 5. f(x)=7x^4+5x^3+3x

Graph each function, then describe its end behavior. 1.-5x^3-2 2.x^2+1 3.x^5-2x^2+2
