Answer:
Step-by-step explanation:
domain X is real number
range Y larger or equal to -3 (cause 4x^2 is always >= 0)
Answer:
Step-by-step explanation:
x^2 + x^2 = 128 Normally you don't do this but rewrite the question
1x^2 + 1x^2 = 128
You actually do use 1 + 1 = 2 First time I've ever done that.
2x^2 = 128 Divide by 2
2x^2/2 = 128 / 2
x^2 = 64 Take the square root of both sides
sqrt(x^2)= sqrt(64)
x = 8
The answer is B. The closer the r value is to 1 or -1, the better the fit is. If the r value is negative, the slope is negative. If the r value is positive, the slope is positive.
