Step-by-step explanation:
Answer:
step by step as shown
Step-by-step explanation:
f(x) = x²-1
f(5) = 5² - 1 = 24
f⁻¹(x)
y = x²-1
x = y² - 1 swap x and y
y² = x+1 ... x+1 ≥ 0 x≥-1
y = √x+1
f⁻¹(x) = √x+1
f⁻¹(8) =√8+1 = √9 = 3
Answer:
slope = - 2/3,y = -2
Step-by-step explanation:
- Make y the subject of the line 3y + 6 = -2x.
- Divide throughout by three to get the slope.
- Get the y - intercept by substituting x = 0.
- The slope gotten is -2/3.
- The y - intercept is y = - 2.
- in plotting the graph, make a point at - 2 on the y - axis which is the y - intercept. Then count three steps from the origin on the x - axis towards the negative direction and mark a point on - three.
