The ordered pair (x,5) is a solution to the function f(x) = x^2 + 1

Mathematics

Answer:

x = ± 2

Step-by-step explanation:

Given

f(x) = x² + 1 and (x, 5 ) is a solution then f(x) = 5

Equating the two gives

x² + 1 = 5 ( subtract 1 from both sides )

x² = 4 ( take the square root of both sides )

x = ± \sqrt{4} = ± 2

Thus (- 2, 5) and (2, 5) are solutions

Given four functions, which one will have the highest y-intercept?
beks73 [17]
<span>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, h(x)=4^0+3=1+3=4
Thus the y-intecept is 4.

D. j(x) = 10(2)^x
when x = 0, j(x)=10(2)^0=10(1)=10
Thus, the y-intercept is 10.

Thereforen the function with the highest y-intercept is j(x)=10(2)^x which has a y-intercept of 10.
