💡 Hint

Common Mistakes

Using a misleading function name like 'squareRoot' when squaring.

Choosing a generic name like 'multiply' that doesn't specify the operation.

The function name 'square' clearly indicates it returns the square of x.

Fix the error in the function header to correctly define a function named 'greet' with input 'name'.

MATLAB

function [1](name)
    disp(['Hello, ', name, '!']);
end

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using a different function name than 'greet'.

Omitting the function keyword or parentheses.

The function name must be 'greet' to match the intended function definition.

4fill in blank

hard

Fill both blanks to define a function 'multiply' that takes inputs 'a' and 'b' and returns their product.

MATLAB

function [1] = multiply([2], b)
    [1] = a * b;
end

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using inconsistent variable names between function header and body.

Forgetting to name the output variable.

The output variable is 'result' and the first input variable is 'a'.

5fill in blank

hard

Fill all three blanks to define a function 'maxValue' that returns the maximum of two inputs 'x' and 'y'.

MATLAB

function [1] = maxValue([2], [3])
    if [2] > [3]
        [1] = [2];
    else
        [1] = [3];
    end
end

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using the same name for output and function name.

Mismatching input variable names in the function header and body.

The output variable is 'maxVal', inputs are 'x' and 'y', and the function compares x and y to return the maximum.
