Find the values of x for which the combined function h(x) = is undefined if f(x) = 5x + 1 and g(x) = x2 - 9.

x = 3

x = -3

x = ±3

x = ±9

Question

Find the values of x for which the combined function h(x) = is undefined if f(x) = 5x + 1 and g(x) = x2 - 9.

x = 3

x = -3

x = ±3

x = ±9

What is h(x)?

geerky42 · Answer

How was functions f(x) and g(x) "combined"?

geerky42 · Answer

Divide, right?

geerky42 · Answer

$$h(x)=\dfrac{f(x)}{g(x)}$$Yes?

rhystic · Answer

are f(x) and g(x) divided or multiplied or what. Assuming division due to undefined then you just need to plug in the values and whatever for g(x) yields 0 creates an undefined combined equation as you can't divide by 0.
