Score on last attempt:1 out of 4 Score in gradebook:_2 out of 4 Suppose f is a linear function and f(x) varies at a constant rate of change of 1.5 with respect to a. Suppose we know that f(1.4) 2.4 a. Suppose z varies from 1.4 to 1.5 i. How much did x change by? ii. What is the corresponding change in f(x)? Af(z) Preview iii. What is the value f(15)? * Preview b. Write a function formula for f(x). (Hint: use the same thinking as in (a), but now imagine z varying from 1.4 to any new value of z.) f(x)- 「ft Preview syntax error Submit
