Which function has real zeros at x = 3 and x = 7?
A
f(x) = x2 + 4x – 21B
f(x) = x2 – 4x – 21C
f(x) = x2 – 10x + 21D
f(x) = x2 – 10x – 214

Which function has zeros at x = −2 and x = 5?
A
f(x) = x2 + 2x − 10B
f(x) = x2 − 2x − 10C
f(x) = x2 + 3x − 10D
f(x) = x2 − 3x − 107

The function h(x) is quadratic and h(3) = h(–10) = 0. Which could represent h(x)?
A
h(x) = x2 – 13x – 30B
h(x) = x2 – 7x – 30C
h(x) = 2x2 + 26x – 60D
h(x) = 2x2 + 14x – 60Did you find these answers helpful?
