3. Given that x + 3 is a factor of the polynomial P(x) = x4 + 3x3 + cx2 - 7x + 6, determine the value of c. Then, factor the polynomial fully. 4. When f(x) = x3 - 7x2 + kx + 17 is divided by x - 5, the remainder is 2. Determine the value of k. Exponential and Logarithmic functions 1. Match each of the following equations with its graph. a) y = 5(2*) + 1 b ) y = ( ) x+5 c) y + 1 = 25-x d) y=5 () A B C D
