Question

For questions 3-5, write a quadratic function in factored form that has the following characteristics.

3. a function with x intercepts at x=4 x=10

4. a function with x intercepts at x=-5 and x=3

5. a function with y intercept at y=8​

Answer 1

4. (a) y=12x²-18x. le + y = 0

(b) y=2ײ-6×-8

○=12x²-18x. 0=2ײ-6×-8

6x(2×-3) =0. 2(ײ -3x -4)=0

6x=0 2x-3=0. 2(x-4) (×+1)=0

x=0. 2x=3. x-4=0 x+1=0

x=3/2. x=4 x=-1

5. y=2 (0)²-7(0)+9

y=9
