Question

For the function y = (4x - 3)(x + 7) the 2 x-intercepts are?

Answer 1

Answer:

3/4 =x        -7=x

Step-by-step explanation:

y = (4x - 3)(x + 7)

To find the x intercepts, set y=0

0 = (4x - 3)(x + 7)

Using the zero product property

0 = 4x-3    0=x+7

3 = 4x           -7=x

3/4 =x        -7=x

Answer 2

Answer:

x - intercepts are (3/4 , 0) &  (-7 , 0)

Step-by-step explanation:

y = (4x - 3)(x + 7)

At x-intercept, y=0

(4x - 3)(x + 7) = 0

4x - 3 = 0    ;  x + 7 = 0

  4x = 3       ; x = -7

    x = $\dfrac{3}{4}$      ; x = -7
