Question

If f(x) = 3x+ 5 and g(x) = – 2x2 – 5x + 3, find (f + g)(x). ​

Answer 1

Answer: 1/8

Step-by-step explanation:(f‌‌‌‌‌‌‌÷g)(x) =

f(x) / g(x) =

2x / 22x

When we divide expressions with like bases, we subtract the exponents.

2(x - 2x) =

2-x

Now we substitute x = 3

So (f‌‌‌‌‌‌‌÷g)(3)

2-3

When we have a negative exponent, we perform the reciprocal of the expression and remove the negative sign from the exponent.

1/(23) =

1/8
