The function has a y-intercept of (0,-1). Step-by-step explanation: The given function is f(x) = x - 1 (1) Now, we have to choose from the statements given in options that best describe the function. I think option 3 is the only statement that describes the function well. Option 3 states that the function has a y-intercept of (0,-1). If we put x = 0 in the function then will get y = - 1. So, the function (1) has a y-intercept at (0,-1). (Answer)

true

step-by-step explanation:

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
