Answer:
function
A set of ordered pairs where each first element is paired with one and only one second element and no element in either pair is without a partner.
Step-by-step explanation:
Question 1: Calculate the slope, x-intercept and y-intercept of a linear equation, f(x) = 5x + 4 ?
Solution:
Given,
f(x) = 5x + 4
The general form of a linear equation is,
f(x) = mx + c
So,
Slope = m = 5
Substitute f(x) = 0,
0 = 5x + 4
5x = -4
x = −45
The x-intercept is (−45, 0)
Substitute x = 0,
f(x) = 5(0) + 4
f(x) = 0 + 4
f(x) = 4
The y-intercept is (0,4)
