Question

If you could pls help me with 22 and 23

Answer 1

Answer:

a) -1 and 5 (option D)

`b)\text{ }As\text{ x }\rightarrow\infty,\text{ f\lparen x\rparen}\rightarrow\text{ }\infty\text{ \lparen option A\rparen}`

Step-by-step explanation:

Given:

A parabola graph

To find:

a) The zeros of the graph

b) The end behaviour as x tends to infinity

a) Zeros of a function is the value of x when the function is equal to zero.

To determine the zeros of a parabola on a graph, we will check for the value(s) of x where the line crosses the x-axis

From the graph, the line crosses the x-axis at x = -1 and x = 5

Zeros of the graph: -1 and 5 (option D)

`\begin{gathered} b)\text{ As x tens to infinity, the function f\lparen x\rparen has an arrow pointing upwards \lparen indicating infinity\rparen}\rightarrow\infty \\ As\text{ x }\rightarrow\infty,\text{ f\lparen x\rparen }\rightarrow\text{ }\infty\text{ \lparen option A\rparen} \end{gathered}`
