The y-intercept of a function is given by the initial value of a function. It is the value of the function when x = 0.
Given the functions
A. Blake is tracking his savings account with an interest rate of 5% and a original deposit of $6.
The y-intercept for this function is the initial deposit which is $6.
B.
x g(x)
0 6
1 2
2 10
The y-intersept for this function is 6 which isthe value of the function g(x) when x = 0.
C. The function h of x equals 4 to the x power, plus 3
When x = 0, [tex]h(x)=4^0+3=1+3=4[/tex]
Thus the y-intecept is 4.
D. j(x) = 10(2)^x
when x = 0, [tex]j(x)=10(2)^0=10(1)=10[/tex]
Thus, the y-intercept is 10.
Thereforen the function with the highest y-intercept is [tex]j(x)=10(2)^x[/tex] which has a y-intercept of 10.
