Question

Graph the function f(x) = 7 + 4x. Then find the value of f(x) when x = 1/2

Answer 1

f(x)=8+4x

f(1/2)

• 7+4(1/2)
• 7+2
• 9

Graph attached

Answer 2

• See below

Explanation:

Given function:

• f(x) = 7 + 4x

The graph is attached

The value of the function when x = 1/2 is:

• f(1/2) = 7 + 4*(1/2) = 7 + 2 = 9

This is reflected on the graph as well
