K(x) = (1/2)ˣ
Since a (=1/2) is < 1, this exponential function is decreasing .
y-intercept for x = 0
k(x) =(1/2)⁰ → k(x) =1, then y-intercept = 1
Horizontal Asymptote:
lim k(x) = (1/2)ˣ = 0
x→∞
Horizontal asymptote x = 0
X intercept (2,0)
Y intercept (0,-1)
Answer:
300
Step-by-step explanation:
Sum the parts of the ratio, 3 + 4 = 7 parts
Divide the total by 7 to find the value of one part of the ratio.
700 ÷ 7 = 100 ← value of 1 part of the ratio, thus
3 parts = 3 × 100 = 300 ← number of girls
4 parts = 4 × 100 = 400 ← number of boys
