- The value of x for which f(x) = 0 is 3.5
- The answer in part a shows that the y-intercept of graph f(x) is at (0, -7) while part (b) shows that the x-intercept of the graph f(x) is at (3.5, 0)
Given the function f(x) = 2x - 7
a) To compute f(0), we will simply substitute x = 0 into the given expression as shown;
f(0) = 2(0) - 7
f(0) = 0 - 7
f(0) = -7
Hence the value for f(0) is -7
b) For f(x) = 0
Substitute f(x) = 0 in the expression as shown;
0 = 2x - 7
-2x = -7
x = 7/2
x = 3.5
Hence the value of x for which f(x) = 0 is 3.5
c) The answer in part a shows that the y-intercept of graph f(x) is at (0, -7) while part (b) shows that the x-intercept of the graph f(x) is at (3.5, 0)
